I have kept playing around and think I found a way around it. I ran in Windowed mode and evrything worked. I think it has something to do with the fuel window in full screen mode so If I turn off the fuel window in the cfg file I think it will work in full mode. Sorry to takw up your valuable time but like I say I don't sit around waiting for a solution I keep trying, must be my 40+ years with computers, the big ones not desktops. Thanks very much for your time and I will definitely buy this product it is so awesome.
