This started happening a few weeks ago when ever I right-click to "Change Desktop Background..." or go into the System Preferences window. In both cases, the 'Deskop & Screensaver' window is CRASHES (a.k.a "unexpectedly quits"). When I go with "Change Desktop Background..." System Preferences quits immediately. When I go through System Preferences --> Desktop & Screensaver, the Desktop & Screensaver window shows for a split second then it quits. This really is crappy & very annoying. Can anyone shed some light on this and maybe how to fix it?
