Hi Mike,

Thanks for the quick reply. I forgot to mention at the outset that AFPD runs fine in a window... it's only full-screen that has problems. And I tried several other full-screen resolutions; they all had the problem.

This was an all-new system with a clean Windows 7 install. The monitor has a native 1920x1200 resolution. And no, I didn't uninstall the previous ATI driver, I just ran the Catalyst 10.12 download. I didn't mention that I had the same problem with the previous ATI driver version... in fact that's why I installed the latest. Also, I have a copy of FSOne (original version) that I installed as a test. It has problems too.
