Mouse Problem (Win7)

[Volkier]

I am having an issue with where the X axis of my mouse is retardedly slow, while the Y axis functions as normal. Upping the sensitivity keeps tract of this - so vertical movement shoots my view up and down, yet horizontal movement is still stuck. Would anyone have been able to fix this very annoying and frustrating issue in the past? I'm guessing it's a Win7 problem.

Cheers.
