I can't open the Security preference pane in System Preferences. I can open desktop settings, spotlight, exposé & spaces etc just fine, but the moment I click 'Security', I get the spinning beach ball, system preferences freezes and I have to force shut it down. I made a quick video using Screenflow to demonstrate the issue (the beach ball doesn't seem to appear in the video .. it did though) http://dl.dropbox.com/u/2264334/Preference%20Pane%20Issues.mov I tried repairing the permissions. Didn't work. Any other suggestions?
