Can't Run?

Cracktastic

Since I installed beta 3, every time I hit a key other then move forward or fire, I automatically start walking and I can only start running again if I hit the walk key. This is really annoying, can you tell me how can I resolve this?

I'm using Pentium III 1000mhz, 256 ram, radeon 9200 128 mb ... don't know if it matters anyway
