Can you point me to this? Perhaps I can test and verify the problems, I
might be able to help...

OK; the idea is this. You differentiate between situations where it's
desirable to lock the game into a closed loop (with only updatestage to
ensure that visuals update), and situations where you simply fall back on
normal ExitFrame loops. You isolate all your game code so that it can be
called as just one handler, say 'GameUpdate': (pseudo-ish code)

  global AllowLoop

  if AllowLoop then
    repeat while AllowLoop
      GameUpdate()
      CheckForLoopDisablers()
      updatestage
    end repeat
  else
    GameUpdate()
    CheckForLoopEnablers()
  end if

  go to the frame

As stated previously in this thread, CheckForLoopDisablers would see if the
mouse loc had moved (perhaps consistently for more than one frame) and then
would set AllowLoop to FALSE; CheckForLoopEnablers would only ever run in
the 'open loop' and would be looking for the mouse loc to stay still for a
grace period of maybe 2 seconds before setting AllowLoop to TRUE.
