I've written a cross platform game that uses [free]glut for a faux fullscreen mode. Since the controls are completely mouse controlled, it's easy to hit one of the hot corners and cause the window to be taken out of focus or off the screen altogether. This was embarrassing when I took my game to a coding competition and users would sometimes hit a hotcorner unknowingly causing them to get confused. Can they be pragmatically and temporarily disabled through code? Preferrably C++ or Obj-C. I've done some searching, and haven't found anything so far. Any ideas? Thanks, shogun.
