This works on W7 7600 x64 just fine, except that when I try to minimize the window, ie exit fullscreen mode, the screen turns black and Windows is unresponsive. Task manager, Esc or any other keyboard shortcuts have no effect. If I can't play in a window then it's pretty useless to me. I even tried looking for the settings file to see if I could force the game to start minimized but no luck. Anyone else able to confirm this bug?
