Mac OS X - System Preferences Panel Won't Open
I am working on the System Preferences panel. It works fine on some computers, but on other Macs (everything works 10.5.5) the preference bar refuses to load and just hangs, pasting the following into the console:
11/9/08 8:38:50 PM [0x0-0x31031].com.apple.systempreferences[369] Sun Nov 9 20:38:50 Macintosh.local System Preferences[369] <Error>: Failed to create window context device
11/9/08 8:38:50 PM [0x0-0x31031].com.apple.systempreferences[369] Sun Nov 9 20:38:50 Macintosh.local System Preferences[369] <Error>: CGWindowContextCreate: failed to create context delegate.
11/9/08 8:38:55 PM [0x0-0x31031].com.apple.systempreferences[369] Sun Nov 9 20:38:55 Macintosh.local System Preferences[369] <Error>: Failed to create window context device
Any ideas why this is happening?
Thank.

It is possible, very likely, that the preference file associated with a particular system preference area is corrupted.
You can try to delete the linked preference file with closed system preferences from your user ~ / Library / Preferences / folder and restart your computer. Typically for Apple System preferences, this file will be ~ / Library / Preferences / com.apple.systempreferences.plist.

I know this is an old thread, but I always post the answers I just did for archiving the answers and other people may have a problem.
Usually when you have a Prefpane account not loading the error, it usually happens because there are 2 guest accounts on the computer. First, go to Macintosh HD (or root hard drive name) and navigate to the Users folder. Go here and see if you have more than one guest account. Then make sure you are not logged into the guest account, open a terminal and enter:
sudo dscl. -delete / users / guest1
This should delete another user account and try to open the prefpane account.
