Hi, For a little while now my desktop & screen saver preference pane hasn't been working. I've been able to bypass it desktop-wise by simply right clicking images and setting them as my desktop wallpaper. However, I've gotten tired of having to do that and I'd like to get functionality back. Basically, if I go into System Preferences and click the icon, the computer freezes for a few seconds and then the entire System Preferences window closes. No error, no result, nothing. I opened console and performed the actions again and received the following lines: Code: 2/20/12 3:00:04 PM System Preferences [NSPrefPaneBundle instantiatePrefPaneObject] (/System/Library/PreferencePanes/DesktopScreenEffectsPref.prefPane): should only be called once 2/20/12 3:00:14 PM com.apple.launchd.peruser.501 ([0x0-0x21021].com.apple.systempreferences) Job appears to have crashed: Segmentation fault 2/20/12 3:00:15 PM ReportCrash Saved crash report for System Preferences version 7.0 (7.0) to /Users/Eskimio/Library/Logs/DiagnosticReports/System Preferences_2012-02-20-150015_Eskibook-Pro.crash I was going to post the log file but it's over 35000 characters (the limit is 20000) so I'm unsure what to do. Any help is greatly appreciated, thanks! Edit: I attached the log file in hopes that it'll help at all. If I need to post the contents in an actual post, I'll split it up and make two posts out of it.
