--- Comment #7 from Tobias Jakobi liquid.acid@gmx.net 2008-02-20 08:21:18 --- I can verify what Jan said. I'm now applying the same hotfix as with the HL engine (switching the keyb layout to US prior to starting the game).
I'm going to try another DX6 game in the next few days (System Shock 2), maybe the problem also appears there.
