General Mac Questions

How do I determine what system software I have?
Under the Apple menu, choose About This Macintosh (About This Computer if you are using a Mac Clone). In this window it will tell you which version of the system software you are using, as well as how much system memory (RAM) you have.
How do I tell if I already have the software necessary to connect to JVLNET installed?

In the Apple menu, choose Control Panels. In order to connect to JVLNET, you need two system components: an item with either Mac TCP or TCP/IP, and an item with PPP in its name (Config PPP, Mac PPP, Free PPP, PPP, etc.). One exception to this rule is the Apple Internet Connection Kit (AICK). If the AICK is installed, you'll still need to see that either Mac TCP or TCP/IP is installed, but Config PPP will be hiding elsewhere in your system. To determine if you have AICK, look in your launcher. You should find something called Apple Internet Dialler. If you can't find it, you don't have the AICK installed.

I get a message saying: "A connection was established but it is not a reliable connection and was terminated" when I try to dial into JVLNET. What can I do to get connected?
There are a couple of things you can do:

  1. First of all, double-check your JVLNET username and password. Make sure you are entering your username and password in all lower case with no spaces. If you have doubts, contact the JVLNET Customer Service Department (1-888-758-8750) and verify your username and password.
  2. If there are no problems with your username and password, the next step is to try a modem initialization string. Try locating your modem in the Modem Init Strings list and enter the information into your dialer. For specific instructions on where to enter the modem initialization string, choose your dialer: ConfigPPP, FreePPP. If you are using the Apple Internet Dialer, or Open Transport/PPP, click here for information.

What's a CCL?
CCL files are modem scripts. The Apple Internet Dialer and Open Transport/PPP (OT/PPP) use CCL files in order to configure your modem to dial into JVLNET. Apple supplies you with a bunch of CCL files, and your modem manufacturer should include one on the installation disk that comes with your modem. Since CCL files are relatively new, you might not have received a CCL file from your modem manufacturer. If in doubt, contact the modem manufacturer and ask them to send you the necessary installation disk.

Why do I get this message? "PPP Wait Timeout - Waiting on: OK"
Here are two common causes of the PPP Wait Timeout - Waiting on: OK error:

  1. Possibly an incompatible Port Speed has been selected. Most likely the selected port speed is higher than what your modem is able to support. For Mac/modem configurations that don't support the 115K or 230K port speeds, stick with the 38400 or 57600 rates as these should be supported by every 14.4 and 28.8 modem on the market today.
  2. There is software installed on your system that is conflicting with FreePPP or MacPPP. To fix the problem, try this:
    • Open the Apple Menu.
    • Open the Extensions Manager.
    • Set your extensions to all off.
    • Select ONLY the necessary extensions to get connected: TCP and PPP extensions and control panels. If you are using OT/PPP, select modem control panel as well.
    • Restart your computer and try connecting through the PPP control panel. The error message will be gone. If there are other problems with your dial in settings, they will show up now and should be resolved before proceeding
    • Once you get a reliable connection, go back to the extensions manager, reactivate the first five extensions, restart your computer, and try connecting again.
    • Repeat the above step for the rest of the extensions, five at a time, until the timeout error returns. It is wise to proceed through the rest of the extensions five at a time because there may be multiple extensions or control panels causing the conflict. Also bear in mind that this procedure is time consuming, so set aside a full afternoon or evening before beginning.
    • Deactivate the group of five that brings up the message, reactivate them one at a time and restart each time. When you find the one that causes the error message, leave it deactivated.

When I start an application (such as Netscape Navigator) it starts to load, but it quits with a message: "An error of Type 1" occured. What can I do?
An error of Type 1 is a dsBusError. Please check to see if it is one specific site that is causing a Type 1 error, or all sites. When the Web page starts to load, hit the STOP button at the top. Try another Web page, such as www.jps.net or www.yahoo.com. If the problem occurs on just one site, there may be an issue with Java and the Netscape version you are running.
Typically, Type 1 errors can be fixed by resetting the connection software and running Disk First Aid. When you have completed Disk First Aid, open the Hard Disk, then the System folder and do the following::

  1. Locate and throw away the file MacTCP DNR.
  2. Open the Preferences folder:
  3. Locate and throw away the files MacTCP Prep and/or TCP/IP Preferences, and PPP Preferences.
  4. Open the Netscape folder:
  5. KEEP these files: Mail, News, Java, bookmark.html, and address.html. Throw everything else away.
  6. Restart the computer. (Under the SPECIAL menu, choose RESTART).
  7. When the computer is restarting, hold down the Apple and Option keys until you get a message about rebuilding the desktop. Click OK.
  8. Check your Network settings. You should have either TCP/IP or MacTCP
  9. Check your dialer settings. You should have one of the following: AICK, ConfigPPP, FreePPP or Open Transport/PPP.

Following the steps above should fix the problem. If the Type 1 error persists and you are on a System Software version 7.5.2 or earlier, it is recommended you upgrade to version 7.5.3 or higher.

I am getting an error of Type 11. What can I do?
An error of Type 11 is a dsMiscErr, or a miscellaneous hardware exception error. In PowerPC's this message replaces the error of Type 1 message, and usually can be fixed in the same manner. Click here to see how to fix a Type 1 error.

When I open a particular program, I get an error of Type 39. What can I do?
An error of Type 39 is eofErr. Essentially, it means the file is corrupt. To fix this problem, do the following:

  1. Locate the file you are having trouble with and throw it away.
  2. Open the System folder. If the file that is corrupt is MacTCP, throw away the MacTCP DNR file as well.
  3. Open the Preferences folder and throw away the preferences file that corresponds with the corrupt file (ex. if the corrupt file is ConfigPPP, trash the PPP preferences).
  4. Restart and reinstall the file you trashed.

If following the steps above does not fix the problem, you will have to replace the actual file (either MacTCP or FreePPP).

FreePPP doesn't Autodetect my modem. What can I do?
If your modem is new, it may not be part of the PPPAutoDetectDB (database) on your computer. The latest PPPAutoDetectDB is available at http://www.macdownload.com. Simply replace your old PPPAutoDetectDB (in your System folder, under the Preferences folder) with the newer PPPAutoDetectDB.
If FreePPP still doesn't autodetect your modem you will need to use a modem-specific initialization string. Click here for JVLNET's listing of modem initialization strings.

When I try to log on to JVLNET, my Connect (or Open) button is grayed out, and I can't click it. How can I connect?
Often this is an indication that your software is installed improperly. Review the setup instructions for your dialer. If everything is installed correctly, try the following procedure:

The Restart Trick
(Only works with MacTCP)

  1. Open your Hard Drive.
  2. Open your System folder.
  3. Open your Control Panels.
  4. Open your MacTCP control panel.
  5. Click LocalTalk.
  6. Close MacTCP.
  7. Leave all the windows open.
  8. Go under the Special menu and choose Restart.
  9. When your computer comes back up, open MacTCP.
  10. Click FreePPP (or PPP).
  11. Close the Control Panels folder.
  12. Locate the MacTCP DNR file and put it in the Trash.
  13. Open the Preferences folder.
  14. Locate the MacTCP Prep file and put it in the Trash.
  15. Under the Special menu, choose Empty Trash.
  16. Close all of the open windows.
  17. Choose Restart from under the Special menu.
  18. While you are restarting, hold down the Apple and Option keys.
  19. The computer will show a message: Are you sure you want to rebuild the Desktop? Click OK.
  20. When it's finished, you'll need to close all open windows.
  21. Check your Network settings. You should have either TCP/IP or MacTCP.
  22. Check your dialer settings. You should have one of the following: AICK, ConfigPPP, FreePPP or Open Transport/PPP.

If you still are getting a gray button after following the steps above, you can run Disk First Aid or try Zapping the PRAM.

How do I connect to AOL using JVLNET?
AOL 3.0 for Macintosh—To configure AOL to connect via your ISP (using TCP/IP) do the following:

  1. Sign off America Online.
  2. On the Sign on Screen (the first thing that comes up when starting AOL), select TCP (for LAN or ISP) from the Select Location drop-down box.

To use, establish your JVLNET connection first, then bring up AOL, and login as normal. It should recognize that the connection has been established already.

AOL 2.7 for Macintosh—To configure AOL to connect via your ISP (using TCP/IP) do the following:

  1. Sign off America Online.
  2. On the Sign on Screen, select TCP Connection from the Locality drop-down box.

To use, establish your JVLNET connection first, then bring up AOL, and login as normal. It should recognize that the connection has been established already.

In TCP/IP, what does the box for Search Domains do?
When you type an entry in the Search Domains field, your TCP/IP application (like Netscape) will look in those domains first, and then search the DNS records.
For example, if you add jps.net to your search domains, and then type www in Netscape Navigator, it will first look in jps.net for www, and it will find www.jps.net.

When I try to install Mac TCP in my control panels, I get the message "Mac TCP could not be copied because an invisible copy already exists." What's happening?
This message usually appears when you already have TCP/IP in your control panels. When TCP/IP is active, Mac TCP is rendered invisible. So, even though you can't see it, Mac TCP is still in your control panels. In this case, you don't need to use Mac TCP. TCP/IP works much better.
If you get this message, and you can't find TCP/IP in your control panels, either call JVLNET tech support or take your computer to an authorized Apple repair station for assistance.

What's the difference between Mac TCP and TCP/IP?
Mac TCP and TCP/IP perform the same function. If you have one, you don't want or need the other. Mac TCP is the older of the two, and is sent out by JVLNET with the floppy disk version of our software. TCP/IP is part of Open Transport. On system 7.5.3 and higher, TCP/IP is integrated into the system software.
If you are using system 7.5.3 or system 7.5.5, you may only see Mac TCP in your control panels. Don't worry, TCP/IP is there, just not active. To activate it, do the following:

  1. Open the Hard Drive.
  2. Open Apple Extras.
  3. Open Network Software Selector.
  4. Check Use Open Transport and restart your computer.

Inside your control panels, TCP/IP will be active, and Mac TCP will be invisible.

After installing System 7.5 Update 2.x on my Macintosh, I noticed the file "MacTCP DNR" in the System Folder. What does the Mac TCP DNR file do? Do I need it?
MacTCP DNR is a special file that contains resources for TCP applications written for System 6.0.x. It's placed at the root level of the System folder because older applications expect it to be available there (like older System 6.0.x control panels).
You may or may not need Mac TCP DNR. It is a good idea to leave it installed because some older TCP applications require it. If you do remove the MacTCP DNR file, it will be recreated automatically after you restart your computer.

What does this mean?: "PPP Modem Connection Failure."
Config PPP gives this error when there is not a dial-tone detected by the modem. Check the telephone cord connected into the modem and make sure that it is plugged into the right port If the problem persists, connect a telephone to that line and check for the dial-tone that way.

Why does my computer attempt to connect randomly?
This should only happen if you are using MacTCP. There is an internal timer in MacTCP that will cause a connection attempt approximately 5.5 hours after a session is closed. You can eliminate this problem if you have FreePPP 2.5 or ConfigPPP 1.0x, because they have options which require all sessions to be manually opened.
If you have FreePPP 2.5, do the following:

  1. Go to FreePPP Setup.
  2. Under the General tab, uncheck Allow applications to open connection.

If you have Config PPP 1.0.x, do the following:

  1. Open ConfigPPP.
  2. Check Disable Auto Connect.

Why don't I connect at the full speed of my modem?
The connect rate reported at logon is just a snapshot of that moment. Your actual rates will fluctuate up and down during the time you are connected. Normal connect rates on analog lines will be between 21.6 and 28.8. It is difficult to achieve 33.6 connect rates on analog lines. Below are some suggestions to speed up your connection:

  1. You may want to run a dedicated line from your computer phone jack straight to the phone box on your house, bypassing other house phone jacks and circuits that may be causing line noise or other interference.
  2. Check your modem setup - make sure the Baud rate is 115k, Data compression is On, and Flow control is set to Hardware. These settings can cause connection problems. If you do experience problems, set the port speed (baud rate) and compression settings back to normal
  3. For more information, consult the following Web site: http://www.houston.tx.us/internet/28800-baud.shtml

Eudora

When I check my email in Eudora, I get an error message that says: "-ERR Maildrop Lock Busy. Is another session running?" What does this mean?
This message appears if you are checking mail and someone else is trying to check email on the same account. It might appear if you check your mail once, and then check it again very quickly. The best thing to do is to wait ten minutes, and try again.
If the error persists, you should contact JVLNET technical support, tell the technician you have a poplock, and request it be reset. Inform the technician that you have already tried waiting 10 minutes for it to reset.

When I check my mail in Eudora, I get a message that says: "That Pesky MacTCP is Acting up Again." What does this mean?
This error means that Eudora cannot find the Internet. Chances are you never got connected. To get connected, try the following:

  1. Attempt to connect directly through the PPP control panel. If there is a problem with your set-up or with the network, a specific error message regarding the problem will be returned to you.
  2. Open either the MacTCP or TCP/IP window from the Control Panels. When you first open Mac TCP there will be a list of items. When you open TCP/IP, there is a configuration setting at the top that says: Connect via:. When you click and hold on the Connect Via: popup menu, you will have a list of items just as in the MacTCP window. Normally, the list will include LocalTalk and FreePPP. It is OK to have PPP or MacPPP instead of FreePPP. Some newer Macs will also have Ethernet listed.
  3. Make sure that you only have ONE type of PPP installed.
  4. Make sure that there is no form of SLIP installed either.

If the problem persists, call JVLNET technical support.

Can I use Eudora to send mail from Netscape, instead of Netscape's own mail program?
Yes. There's an AppleScript, called Eudora Mailto Helper, that will let you use Eudora as the mail-sending program for Netscape.
To run the AppleScript once you've downloaded it, do the following:

  1. Quit Eudora (and Netscape if you're running it).
  2. Find the file called "netscape-eudora-mailto.as" on your hard drive and double click on it.
  3. When AppleScript comes up, click Run. It may ask you to find Netscape for it. That's it!

Eudora will now come up if you click a mail to link on a Web page in Netscape. -ALSO- If you go to File: New Mail Message in Netscape, it will go to the standard Netscape mail interface and let you type a message, but when you click Send, it will go to Eudora and bring up the message you just typed.
Eudora should be running in the background when you send mail from Netscape for the AppleScript to work properly.

To go back to letting Netscape use its own mail, delete the Netscape prefs file from your system folder.

How do I set up multiple users on Eudora Light?
Before you can set up multiple users, one copy of Eudora must already be configured. Once you are sure that has been done, do the following:

  1. Drag the Eudora folder out from the System folder to another location (anywhere) on the hard disk.
  2. Replace the folder with an empty TeachText file called Eudora Folder (this step prevents another Eudora Folder from being created in the System folder in the future).
  3. Rename the Eudora Folder anything you want (it might be a good idea to name it after the user of the newly created email account).
  4. Make a copy of it and give the copy another name (this can be done for as many as necessary).
  5. Each user will have their own personal mail folder and can launch their copy of Eudora by double-clicking on the Eudora Settings file in their own folder (an alias to that settings file also works well).
  6. Change the POP account information to reflect specfic new POP account addresses.

How do I set up multiple users on Eudora Pro?
Before you can set up multiple users, set up Macintosh Eudora Pro 3.1 and handle extra e-mail accounts with the Personalities feature. Do the following:

  1. Open Eudora. In the Getting Started, Personal Information, and Host screens under Special:Settings, enter configuration information related to the account you use most frequently. This account is the "Dominant" personality
  2. Go to Special:Settings:Personalities and click New.
  3. Fill in the fields with the information for one of your other accounts. Make sure you enter a name for this personality in the Personality: field at the top.
  4. Check the Check for mail every x minutes and/or the Check mail on manual checks box(es) at the bottom if you want Eudora to check mail for this account.
  5. If you want to set up more personalities, click New again, and repeat the process for any other accounts. You can, if you wish, set up more than one personality for each e-mail account. If you do so, make sure that the Check Mail options are checked for only one personality per e-mail account -- otherwise, you'll get multiple copies of your mail.
  6. When you're done, click OK.

Once you have set up personalities, there will be a drop-down menu of personalities in the From: line of your new messages. Use this menu if you want to send mail from a non-dominant personality (so the return address, signature, etc. will be from that personality's settings).

Can you explain the different encoding methods available in Eudora? When in the best time to use each one?
With Eudora Pro, you can send attachments with any of the following methods:

    1. The MIME (Multipurpose Internet Mail Extensions) standard uses Base64 encoding. Base64 is the newest form of encoding and is a good choice for sending files to either Macintosh or Windows computers. While it's the best choice in general (that's why it's the default encoding selection in Eudora), since it is a newer standard, some older mail programs don't support it. If your recipient has trouble reading your MIME attachments, try BinHex or Uuencode.
    In the Macintosh, there are two ways to send MIME attachments, AppleDouble and AppleSingle. (These are both Base64 MIME encoding, just different ways of doing it). If you want to use MIME, it's best to use AppleDouble when sending to Macintosh or PC users.

    • AppleSingle is good for Macintoshes, but shouldn't be sent to PCs. An AppleSingle attachment may not be understood by a PC because it includes both the data fork and the resource fork of the file. The resource fork is useless to a PC.
    • AppleDouble splits files up during transport, so a PC can trash the resource fork and just use the data fork. Since you often don't know what kind of computer your recipient has, AppleDouble is usually the best choice.

2. BinHex is a traditional Macintosh method for encoding of files. It is a good choice when sending Macintosh files to recipients who do not have a MIME compliant mail reader. Uuencode is best used only when the recipient asks for it. This will mainly occur when your recipient is using a UNIX or PC mailer that does not support MIME. Eudora Light does not support Uuencode.


Netscape

When I click on "Get Mail" I get a message saying: "/popper/tmp/.username.pop lock busy! Is another session active?" What does this mean?
A pop lock is a Unix security feature that only lets one person access a POP email account at a time. This message appears if you are checking mail and someone else is trying to check email on the same account. It might appear if you check your mail once, and then check it again very quickly. The best thing to do is to wait ten minutes, and try again.
If the error persists, you should contact JVLNET technical support, tell the technician you have a pop lock, and request it be reset. Inform the technician that you have already tried waiting 10 minutes for it to reset.

I open up Netscape Navigator, and this message pops up saying: "Netscape was unable to create a network socket connection." What does this mean?
This error means that Netscape cannot find the Internet. Chances are you never got connected. To get connected, try the following:

  1. Make sure you are dialing into JVLNET. If you are in doubt, pick up your phone handset and listen. If you get a dialtone, you are not connected. If you hear static, you are on line.
  2. Attempt to connect directly through the PPP control panel. If there is a problem with your set-up or with the network, a specific error message regarding the problem will be returned to you.
  3. Open either the MacTCP or TCP/IP window from the Control Panels. When you first open Mac TCP there will be a list of items. When you open TCP/IP, there is a configuration setting at the top that says: Connect via:. When you click and hold on the Connect Via: popup menu, you will have a list of items just as in the MacTCP window. Normally, the list will include LocalTalk and FreePPP. It is OK to have PPP or MacPPP instead of FreePPP. Some newer Macs will also have Ethernet listed.
  4. Make sure that you only have ONE type of PPP installed.
  5. Make sure that there is no form of SLIP installed either.

If the problem persists, call JVLNET technical support.

Every time I open Netscape Navigator, I get an error message saying "Java Initialization Failed." What does this mean?
This error message usually means that the Java file in your Netscape folder (in the Preferences folder) is missing. The only way to fix this is to delete, and then reinstall Netscape.
If the Java file isn't missing and you get theis error message, you should download the Java Initialization Patch. It is available from Netscape's Web page.
If the problem persists, download a fresh, more secure copy of Netscape Navigator 3.04, which also includes some security fixes for Netscape.

When I check my mail in Netscape Mail, I get an error message that says "An error occured while saving mail." What does this mean?
This normally happens when the Inbox file gets corrupted. You can fix it by following the steps below:

  1. Open the System folder.
  2. Open the Preferences folder.
  3. Open the Netscape folder.
  4. Open the Mail folder.
  5. Locate the Inbox file. (NOT the Inbox.snm file). If you have mail in your Inbox that you want to keep, move it to your desktop. If not, trash this file. You can regain your mail by opening the Inbox file with SimpleText or another text editor. This file will recreate itself when you check your mail the next time.

I open up Netscape Navigator, and this message pops up saying: "Netscape was unable to make a network socket connection. There may be insufficient system resources or the network may be down." What does this mean?
This error means that Netscape cannot find the Internet. Chances are you never got connected. Usually, there isn't a problem - for one reason or another you didn't get connected the first time. Remember, you won't always get connected the first time. Sometimes you will need to dial out a few times before you can get a connection. Likewise, the same problems that plague your regular phone calls plague your calls to the Internet. To get connected, try the following:

  1. Make sure you are dialing into JVLNET. If you are in doubt, pick up your phone handset and listen. If you get a dialtone, you are not connected. If you hear static, you are on line.
  2. Attempt to connect directly through the PPP control panel. If there is a problem with your set-up or with the network, a specific error message regarding the problem will be returned to you.
  3. Open either the MacTCP or TCP/IP window from the Control Panels. When you first open Mac TCP there will be a list of items. When you open TCP/IP, there is a configuration setting at the top that says: Connect via:. When you click and hold on the Connect Via: popup menu, you will have a list of items just as in the MacTCP window. Normally, the list will include LocalTalk and FreePPP. It is OK to have PPP or MacPPP instead of FreePPP. Some newer Macs will also have Ethernet listed.
  4. Make sure that you only have ONE type of PPP installed.
  5. Make sure that there is no form of SLIP installed either.

If the problem persists, call JVLNET technical support.

When I check my mail in Netscape, it says: "Retrieving 1 of 5" and then Netscape quits with an error message that says: "Sorry, an unexpected error occured in Netscape Navigator." What does this mean?
More often than not, this message means the index files that store headers about the email in your Inbox have become corrupted. All you need to do is trash the header files and check your mail again. You will not lose any mail by doing this. Follow the steps below:

  1. Make sure that Netscape is NOT running.
  2. Open your System folder.
  3. Open the Preferences folder.
  4. Open the Netscape f folder.
  5. Open the Mail folder.
  6. Find all of the files that end with .SNM and put them in the trash.
  7. Empty your trash via the Special menu.
  8. Open Netscape and check your mail. If it works, you're done.

If the error message persists when you check your mail, then the Inbox itself is corrupt. To fix the problem, follow the steps below.

  1. Make sure that Netscape is not running.
  2. Open your System folder.
  3. Open the Preferences folder.
  4. Open the Netscape f folder.
  5. Open the Mail folder.
  6. Trash ALL the SNM files again.
  7. Move the remaining files to your desktop. You can open these files with a text editor like SmpleText and save the contents of these files.
  8. Close all the windows and try checking your email again. This should solve the problem.

I can't go to any Web pages or check my email. Every time I start up Netscape, I get an error that says, "Netscape was unable to locate the server www.jps.net. The server does not have a DNS entry. Check the server name in the location (URL) and try again." What does this mean?

  2. If you are getting connected, but the error message persists, you may have a DNS resolution problem. In other words, your system can't find our servers. Check your name server addresses in TCP/IP (or your domain and IP address in Mac TCP) to make sure they are entered correctly.
  3. If all your settings are correct, your system probably has a bad Mac TCP or TCP/IP Preferences file. Follow the instructions below:
    • Open the System folder.
    • Locate and throw away the file MacTCP DNR.
    • Open the Preferences folder.
    • Locate and trash MacTCP Prep. You will NOT normally have this file when running Open Transport TCP/IP.
    • Locate and trash TCP/IP Preferences.
    • Trash PPP Preferences.
    • Open the Netscape f folder.
    • KEEP: Mail, News, Java, bookmarks.html, and addressbook.html. Throw everything else away.
    • Restart your system.
    • Re-setup your PPP dialer (FreePPP, ConfigPPP, Open Transport/PPP) and double check the network settings (MacTCP or TCP/IP)

If the problem persists, rebuild the desktop and run Disk First Aid. If you are on a System Software version 7.5.2 or earlier, it is recommended you upgrade to 7.5.3 or later.
Finally, if that doesn't work, you should perform a clean installation of your dial up software. This is best entrusted to an authorized Apple repair facility.

Netscape Navigator constantly freezes my Macintosh. It's REALLY frustrating! Is there anything I can do?
When a Macintosh totally freezes up, it's hard to diagnose the specific cause. Try the following:

  1. Run Disk First Aid or Norton Utilities.
  2. If you have no errors, you might want to try using an Extention called Netscape Defrost. This Macintosh system extension keeps Netscape for Macintosh from freezing while accessing Web pages.
  3. Many people have reported freezes which require the Cmd-Opt-Esc key combination to force Netscape to quit.
  4. If you would like the details of the crash, visit www.erols.com/delorean/nsdefrost.html and read more.
  5. If the system freezes specifically when you are doing searches, your system might be having problems with Java. Click here for assistance.

I get a message saying that Netscape does not have enough memory to run. Can I do anything aside from purchase more RAM for my computer?
There is no solid substitute for "real" physical RAM installed in a Macintosh, however, you can make some system adjustments to compensate in the meantime. This is a TEMPORARY solution. Virtual memory can cause a whole other host of errors:

Memory Control Panel Settings

  1. Open your System folder.
  2. Double click on the Control Panels folder.
  3. Locate the Memory Control Panel and open it.
  4. You may or may not have the items below. If you do, make the necessary modifications:
    • Modern Memory Managment: On.
    • Virtual Memory: On.
    • Find the built-in memory size and double it using the up and down arrows.
    • RAM Disk: Off.
  5. Close the Memory Control Panel.
  6. Close all the windows you have open.
  7. Restart your Macintosh

Once you have more memory, you need to give some of it to Netscape:

  1. Locate and open the Netscape Navigator folder.
  2. Locate the Netscape Navigator 3.0 file.
  3. Click ONCE on the Netscape icon.
  4. Under the File menu and choose Get Info. At the bottom you will see a section for Memory Requirements:
    • Suggested: This is what the program wants to have. You cannot change this number.
    • Minimum: This is what the program absolutely must have. Try adding 1000 to this number.
    • Preferred: This is how much memory the program will take if it can get it. Try adding 1000 to this number. Visit www.netscape.com for specific recommendations.
  5. Close the Get Info window and try opening Netscape Navigator.

What are cookies, and do they pose me any risk?
A cookie (also called a Persistent Client Side State Object) is a little piece of information handed to a WWW client by a WWW server, containing information that can be retrieved by the server later. For instance, a server can hand your browser a cookie when you fill out a form stating your preferences for visiting that server. Then, the next time you visit the site, the server can read your preferences from the cookie and customize the appearance of the Web site to your preferences.
Do they pose a risk to you?
Keep in mind that these systems mostly rely on information you supply anyway. In a context where you are a regular user or customer, cookies probably work to your benefit. Cookies are often used only to track a specific Web session, and may expire after that visit. They are supposed to be limited to only exchange cookie information with the Web site that originated the cookie data - they use host domain names to manage the data and to limit access to it. Cookies might be saving a flag that says you already entered your password and were validated -- so you don't have to enter the data for every page you access in a given session or perhaps even for future sessions.
If they really make you nervous, try download a freeware utility called Cookie Monster. It deletes all cookies from your system everytime you quit Netscape (cookies aren't saved on your system until you quit your browser). It is available from macdownload.com and various other Mac software sites.

When I check my email, it just sits there. What is it doing?
Normally, this indicates that you have a large message or a slow connection to the mail server. If you look in the upper, left corner and you see the Netscape Logo N is animated (with comets flying though it) you know that Netscape is working. You should not click Get Mail or Stop or you will risk creating a pop lock on your email account. Let Netscape finish, or return an Error Message.
