Weird problem switching weapons?

[ZerG]

So I figured out I can play alot of games on this 785K dsl connection..and i am back on css a little..with a new keyboard but..

When I am running I cannot press "2" on keyboard, for deagle, while running...1, 3, 4, 5 all work and 2 works on other games like bfbc2, mw2 while running, just on css..the switch works if I am standing still but if I am running deagle cannot be swapped to and my mouse wheel is goofy..so i dont even use it..any idea why "2" isn't reading if I am running on CSS? its pretty annoying and idk what it could be


I havnt tried my old keyboard yet because the keyboard I am using is fine on other games and is fine on CSS besides the fact 2 isn't reading while moving ..
