So I've been using the steelseries rival since december and for the most part it's been great, however recently it's started to have a scrapping feeling on my mousepad when I move it sometimes. It does not affect the sensor in any way, but it definitely is distracting. I was wondering if any other steelseries owners have had this issue, and what some solutions might be. I'm considering purchasing new steelseries mice feet. BTW The mouse pad is one of those Steelseries QCK Cloth pads. I'm also thinking it might be the rubber cord rubbing against the wooden desk.
