Do you mean when it does happen, it happens immediatly when GameEx launches? What res are you running gameex at, and what res do you have the desktop at, and how are you launching gameex. Is the Desktop or GameEx running in 16 bit colour at all or switching to and from, that would deffinitly cause this issue. If you run GameEx in 32 bit colour (without this issue) exit and the only change you make is switth to 16 bit colour, it would do this, im sure. Ill fix the problem, but I think that sums it up
