"Shut down computer" not working because SuperDuper fails to quit
 

When I set SuperDuper to shut down my computer after backing up I am often getting an error message: "Logout has timed out because the application SuperDuper! failed to quit. To try again, quit SuperDuper! and choose Log Out from the Apple menu."

I recently changed some settings to make my computer require a password to wake up from sleep, but that's the only vaguely related change I can think of that I made recently.

Running 10.5.8 on an early 2009 Macbook Pro.

SuperDuper version is 2.5. I tried deleting it, and downloading and reinstalling but I get the same error.

thanks
