you need to check the boxes for run as administrator, disable high DPI, disable visual themes, and disable desktop composition. you can leave it so that it still runs under windows 7. I have a state of the art graphics card, and i am running a 64 bit version of windows 7 and the only problem that i have is the loading page will not change over by itself at the start of a new map. i just alt-tab out and back in again and it works just fine for me. if you have any more questions, please feel free to e-mail me at email@example.com and title the subject: MM9 Help, this way i know that it is not spam. hope this helps.
