Okay phew... lot of reports in a short amount of time. I'm not currently at my normal computer right now and a bit busy in the past two days so I'll have to update the list later tonight, after I get back to campus.
Batman55 - you can try waiting to see if Kim will reply in this thread again, he seems pretty knowledgeable about computers and programming.
It sounds as though maybe something's corrupt within the level itself? If it only does that in the Laboratory, maybe you should try re-installing the game and playing without the patch first, then try playing with the patch. (Patching it before launching the game
may have done something to the files, but don't take my word on it).
Anyways, again sorry for the slow updates. I'll get on it tonight.
