I'm not sure how this happened, but I discovered I can no longer search within System Preferences. Typically, I can search for "screen saver" and it would highlight the Desktop and Screensaver group for me, but now nothing shows up. Spotlight results show preference items, but nothing within the System Preferences menu. On the guest account, everything works as it should, which leads me to believe it's a messed up plist file or something. Do any of you know what may have caused this and how I can correct it?
