Once again, binary will let DirectX throw a too high refreshrate in full screen mode, so, black screen!
So be carefull and don't run game (F5), just compile it (F6). Run the binary and use alt+F4 to get out.
First, let's reverse the default fullscreen default (delete the .xml file created when you first launched game)
Retrieve the source (even if it's for xbox360, it compiles well on Windows too)
In Game\BaseGame.cs, at line 1217, "open" the "Constructor" region, and at line 1251
graphics.IsFullScreen = GameSettings.Default.Fullscreen;
graphics.IsFullScreen = !GameSettings.Default.Fullscreen;
