Replace calls to window_close(Game_wind) with returning window_event_result::close to game handler. Applies to when DoEndGame() is called, DoGameOver() is called, aborting in the kmatrix screen (multiplayer game) during AdvanceLevel() and playing one demo frame causes playback to stop in GameProcessFrame(). Closing a window within its handler is problematic - it can result in an unstable state.
