Yes, I have also experimented the "application failure problem". It appears only when developing and sometimes I have to shutdown the system because if I run FoxPro again, I get no mouse.
If the problem is when running an EXE file, you should check other programs running. The problem should not be in FoxPro itself.
Good Luck
