Messed up colors in fullscreen sounds like a driver issue. As for the windowed problem, is whatever shortcut you are using pointing to the .conf file you are editing? The one you posted (the combined .confs for MM3?) still has the game launch fullscreen. Change fullscreen=true to fullscreen=false and save the file. If the game still launches fullscreen then you are editing the wrong .conf or using the wrong shortcut.
JRRNeiklot: I have tried several different resolutions, nothing resizes the window. It is not fullscreen. Fullscreen messes up the colors.
What's your hardware, and monitor if separate, anyway?
