Hey,
Just had a new Deathadder 3500 turn up in the post, and thought "what they heck" and plugged it into my work computer, every now and then the curser seems to just wonder off even when I'm not touching the mouse. Can I account this to the lack of a mouse mat at work and the fact I'm just using the mouse on a shiny desk? When I take it home I'm all mouse matted up so hopefully won't be a problem there =)
