Freeze in Chemical Lab

[B4CK]

Hi there,

I get an annoying bug: when I try to enter the chemical lab, after getting the lab key from the dead guy, my computer freezes.

I mean, one of my two CPU core jumps to 100% and my framerate falls down to 0: I don't know if the program loads the map or what, but sounds are stuck and I can see the chemical lab but I can't move.

Well, freeze is the right word :-)

As info, I played the whole game without getting a bug, so I guess it's not a driver problem :-)

Any idea?
