I downloaded a copy of Xcode just to try it out. When i went to uninstall i dropped it in the trash and it said i couldn't remove it because it was still in use. I opened activity monitor and it wasn't running and when viewed it has no version. It also can't be opened because it is damaged or incomplete. Instruments is also the same way now after i used the terminal command to remove Xcode (.sudo /Developer/Library/uninstall-devtools mode=all) I'm also running Lion if that helps. What can i do to get rid of these two pesky apps?
