I purchased iStopMotion 3 from App Store and have created and saved a short test sequence. When I tested the export to iMovie feature nothing happened – no export dialog like in the Getting Started video. Am I missing a step?
I am using iMovie '11 on a late 2008 MacBook Pro running 10.8.1.
Try running Disk Utility.
