Two questions:
1. Which resolution did you use in Compatibility? Everything I tried was - like you said - clipped. I managed to check the Fullscreen option in-game, but on the next start up, it was clipped even worse.
2. How did you manage Edit mode? No matter what I tried, the game didn't register the mouse clicks. If I choose gamepad mode at start up, the controls barely work and seem to be inverted?! Pressing right makes me walk left for example.
