HOLMESFUTRELL  Opened app for the first time and selected 'import from file'. App spent a long time updating my application's icon. I canceled. Now the app just crashes on 'import from file.'

HOLMESFUTRELL  I don't think icons belong on MacUpdate

HOLMESFUTRELL  Could you tell me more about your system? What kind of hardware, OS, etc?

I have done my best to test POV on a wide range of systems, both PowerPC and Intel, and never during testing did it lock a system up. If you provide me more information I can investigate this further.
