Finder - Cannot double click items to open
If I double click an item with it's default program open, nothing happens. If I double click an item and the program is not open, the program bounces in the dock and does not open.
Same for .dmg files. If I download them, I can only open them using Disk Utility.
These problems are not present when I boot up. They only happen at some point later. A restart fixes the problem.
Anyone else experiencing this?
MacBook, Mac OS X (10.6.1)
