I had energy saver set to put the computer to sleep after 30 minutes & display at 15 minutes.
After pressing any key to wake... I choose an application from the dock but the finder opens, not the application.
I repaired permissions and the same thing happens. Not until I restart does the problem go away.
Anyone have this happen with Leopard on something other than a new MacPro 2.8, 8-core...?
