Der Zeitgeist

I had the same problem yesterday, and remapping the "weapon fire" action definitely did the trick for me. I just put it on the key next to the left shift key (I have a German keyboard, so I don't know what's on there for you) which is not mapped with anything else. The normal space key for firing weapons is still working, too, you just map an alternative, and press that key while you're in training.:thumbup:
