This keeps on happening, I restarted CC, restarted the PC, and nothing. I even changed the resolution many times.
It keeps on messing with the HUD and jamming the map whenever I put a terrain in the shape map editor.
Wtf. Sorry this never happens to me. Must be a system specific error caused by video card / driver problems or simply because BlitzMax is crap. I don't know what to do about it.
