Hi, If I move my mouse fast left or right (but not that fast) the cursor starts moving up or down or some other direction it shouldn't be. It's real frustrating for some games. Is this normal??? It's an optical mouse came with the computer, not USB. I don't remember it doing this before but it's been doing this for a looong time now. I have Win XP SP2, 2 Ghz pentium 4, 1 GB RAM, ATI 9800 128MB, DirectX 9.0c... I hope that's enough info. Thanks.
EDIT: I just had an idea and I'll try it: Could it be that the optical sensor on my mouse might just be dirty? How would I clean it if that's the case? Compressed Air?
