The controls screen is shown during the level loading, so it could be that DBPro hates one of the models it's loading. However that changes depending on the version of DBPro - I find v5.9 works, but the jeep goes crazy, still the best option though.
From my debugging, I came to the conclusion that it was an internal DBPro bug causing those weird loading problems, not ideal I know - perhaps things will work better in 6.0.
Wigget,
Dude, I'll get onto the improved engine soon, just kinda swamped right now with the compo's.
