I have a problem with the latest version and a new computer, i try to change my resolution but it will not work anyway. If i use an older computer it will work just fine. The application will only display in a very small window.

I have a new Lenovo convertible with windows 8 and I have the same problem. On my old XP professional lap top looks big and great.
Please let me know what can be done.

I also had some problems to get it running on W8.
Got it working after installing win drivers and app "as administrator".
Hope it helps for you too, happy flying.
