Just bought iStopMotion Home, won't fire up?

Bit concerned, just bought iStopMotion Home for kids to use over the holidays, downloaded no problem from App Store 5 minutes ago, fired it up from Applications folder, the preview pane comes up, but then we just get the Apple spinning wheel (of doom!) which just… keeps on spinning.

We are on a MacBook Pro 15" running latest Lion OS X.


Hi Tim, we have submitted an update to iStopMotion with full Lion compatibility to Apple more than a week ago and are eagerly waiting to it to be approved. Nevertheless the issue you describe seems very strange, we have never seen anything like that. Even the current version usually works fine on OS X Lion.
The app freezes immediately when starting? A document window and a dialog in front of it comes up? Or just the splash screen with the camera?
