Having this really strange issue, and frankly it's a big pain in my ass. I think I am running the Logitech Cordless Duo here at work. And basically what ends up happening [quite often might I add, about 50 times a day] is that occasionally when I scroll the mouse wheel, it ends up going back on my web browser. Are there any known issues about this? Is there something I can take apart inside of there so the mouse wheel works as it should, but it won't go back? I dont' even know how it sends the signal to go back, there are no other keys on the mouse!
