Mine get like that after while, its Verdigrease from your hands, strip it down and clean all inners.
I currently have a Saitek Gaming Mouse, its just over a year old. When i move pointer/cursor from left to right across screen its movemnet appears somewhat jerky.
Are all mice like this or do smooth move more smoothly?
What are you using as a mousing surface?
The Teflon feet on my Razer Diamondback keep it scrolling smooth - no fancy surface, just a free mouse mat I got with Supreme Commander![]()
The movement across the Matts feels smooth. It just appears jerky on screen! Methinks its the mouse!
Certainly sounds like something is wrong with it, am I correct in saying it's a wired mouse?
