I just launched SuperDuper without my external backup drive attached and got the usual error about not being able to find the drive. Fine. So I quit, mount the drive, and relaunch SD. Unfortunately now the Copy from and to dropdowns are greyed out (see
http://img74.imageshack.us/img74/3366/picture2mw2.png. bembo is my internal drive.) I can click items in the main menue (Preferences, etc.) and the Options and Schedule buttons. However, when I click OK in Options nothing happens and the entire windowed interface stops responding to clicks (the menu still works).
I've tried trashing com.blacey.SuperDuper!.plist and Application Support/Super Duper, but nothing changes. Any ideas?
