Aperture 3 hangs because it's waiting for time machine to backup.
I was trying to export around 50 images and aperture3 hung. I clicked on aperture in the menu bar and it said "Application not responding". I waited and waited and then "force quit" aperture. Now when I try to reopen that library, it says "waiting for time machine to finish backing up library". I stopped the backup and I am still getting the same message. I tried to repair library, but to no avail - still the same message....
I must have force quit aperture during a routine time machine backup.
really need that library! please help if you can...
macpro, Mac OS X (10.6.4), aperture 3
