It's not exactly wrong to edit files in TextEdit--I do it all the time. But it's not recommended, esp for Unix novices. I shouldn't have said it, and I should have been clearer about Psuedo and Terminal.

If you backed up com.apple.windowserver.plist like I said before editing it, then no worries. Just Trash the altered file, and replace it with your backup. Then make another backup. Use Psuedo to open your new com.apple.windowserver.plist file and cut and paste the text I sent you in the previous message as I described, save and exit. You will have to restart your computer for the changes to take effect.

I am curious--when you mention having trouble overwritng the file, did it actually overwrite? The date of the file in the View window will tell you. If it didn't overwrite then I don't think any changes were made. Are you having problems with your system after the overwrite problem?

The Terminal is a command line window that allows you to access the Unix Core of the Mac OS X operating system. It is a very powerful place, and if you know what you are doing you can do incredible things with your computer. You can also jack it up royally if you are not careful. Normally, you can't access files that are part of the core OS X. In fact, you can't even see most of them using the graphical interface (GUI)--to view them you have to use the text based Terminal. You also can't make changes to them unless you are in root or superuser mode-- which is Unix speak for Master of the Universe (also known as the superuser) But to do that you have to logout as your regular account and log back in as root. Even if you are the only user on your Mac, it behaves as if there are multiple users or accounts--each with a password. So to save time, Unix has a shortcut: the sudo command (short for superuser do). You type sudo and either use programs from the sudo command prompt or type a single specific command without having to logout as your User ID and logback in as root, then logout as root and log back in as your User ID. See how useful sudo is already?

Anyway, in usual Mac style, there is a graphical workaround--a shareware program called Psuedo that does what sudo does in the Terminal window from your desktop. Just go to http://personalpages.tds.net/~brian_hill/psuedo.html.
There you can d/l Psuedo. Once you've installed it, open it. Then drop and drag com.apple.windowserver.plist onto Psuedo and it will allow you to alter the file as root.

If you don't have it, then I highly recommend Mac OS X: The Missing Manual by David Pogue. It tells you a lot about the Unix core of Mac OS X. There's also a Unix for Mac OS X which covers Unix basics for beginners, also from Reilly Press (tho I forget the author at the moment).

I'm glad the change to the limewire file went well. Let me know how the rest goes and if I can be of any more help.
