My computer was doing the exact same thing. I have Windows Vista Home Premium. This is the change that I made, and now it works just fine.
1. Right click on 'Aces High II Film Viewer'.
2. Click on 'Properties'.
3. Select 'Compatibilty'.
4. Check the box that says "Run this program in compatibilty mode for:".
5. Select 'Windows 98/Windows ME'.
6. Hit 'OK' and restart the Film Viewer.
I hope this helps you out.
