--- Comment #5 from Stefan Dösinger stefandoesinger@gmx.at 2009-12-20 13:35:05 --- It's possible that the game uses ddraw to query the video memory, and while doing that expects some window messages. Can you collect a +ddraw log? If that doesn't show up anything it is most likely not ddraw related.
