My program crashes even without any mouse movement. I want to display
some information about the status of my calculations by changing the
picture of the MouseCursor, only (e.g. SetMouseCursor(OKCursor)).
After a while, however, the program crashes:
  _GrP8PixCopy+942
  _GrEraseCursor+60
  _rawclock+419
  _MouseSetCursor+63
  ...
If I simply delete the SetMouseCursor()-commands everything works
OK while the default MouseCursor is displayed.
