What Thiev said, or you could try changing the resolution the game is running at to the native resolution of your monitor (will probably be whatever resolution you use for your desktop). I don't actually own this game so I don't know where you'll have to go to change resolution but I hope I helped a bit.

Thanks very helpful- appreciated

I have always found this to be a very helpful forum :)
If you have it all working properly would you like to tag it as closed and one of the helpful folk about as having answered it?

How do I do that?
