I've just started trying out Nexuiz - poking around some maps with bots - and I keep getting stuck going in one of three directions (right, left or back). It's as if the keyboard is stuck because it continues when I'm respawned (which happens a lot since I can't control my dude). It seems to go away if I stop pressing any keys and then press and release just the key that seems stuck. I've tried several keyboards including a brand new one, so I don't think it's actual sticking keys, but I'm not sure what could be causing it. I haven't seen the problem in anything else (although I don't game much).
Any ideas?
TIA
