Hello Schrullenhaft!
Thanks for trying to help us out a bit!
In answer to your queries I have the following:
The CMAK version is the CDV one, I am running Windows XP Home Edition, Video driver 30.82 (is that the right number? I installed it last time for CM2), for the NVidia GeForce4MX420 Card, with DirectX Version 9 running. I have followed your instructions and turned off the antialiasing, although I have NO idea what it was or what it's for! Desktop is running at 800 x 600 with refresh rate of 60Hz. I tried uninstalling and then reinstalling CMAK to see if it made any difference or to see if it would force the screen resolution choice to come up again, but neither of these happened, no difference has been made - it just minimizes straight away again (and then I can't get rid of that!). Please help, v frustrated, Sam.
