Ok I've got a random one for ya.

In Counterstrike 1.6 my mouse sticks constantly when I am looking around. It only occurs if I am holding down 'a or 'd' while looking around, and it sticks/chops across the screen, barely moving at all.
It also does not do this in any other games, like it works fine in tf2

I have tried switching mice. No dice.
I have tried switching keyboards. No dice.
I have uninstalled+reinstalled cs. No dice.
I have tried uninstalling+reinstalling the drivers for both the mouse and keyboard. No dice.

Here's the kicker, it works fine on single player.
Please help me.

is it lag?

lol very odd

cs 1.6 rocks.

edit - sorry for the complete lack of help....dont have a clue.

no it aint lag. im thinkin it's some command, but i have no idea what
