ApplicationsIt sounds like you wrecked the permissions of every file you have. I suggest you restore from the last backup you made before doing that. Otherwise, boot from your installation disc and repair permissions. The reinstall all your third-party software. You may also need to reset the permissions of your home folder.

Jun 16, 2012 5:30 PM in response to Linc Davisby MCDfromchicago,Permissions problems occurred after I downloaded Lion update on 6092012. I believe the problem originates with Lion (see the 19 pages of posted problems in the community). I have now talked with Apple Support rep and an Apple Genius. Have reinstalled Lion from the HD Recovery disk. I see some improvement but also at least one new problem: TimeMachine apparently has lost all backups, don't know how or why. Will have to take machine to a mac specialist or wait for Mountain Lion to arrive. Lion is a bad cat.
