I've been having problems with my new HTPC keyboard where it tends to cause the webpage to wildly scroll up or down randomly while typing on the keyboard or messing around with the optical cursor. I am making sure that i'm very clear away from the scroll bar area.
no, i have had mine for only a week but not had this issue. A question though. Does your keyboard feel spongy? Like it has seperated from the device, and every key moves when you just press a single key?
I've had this issue off and on over the past couple years of having this N5902 controller. I just figured out that my issue was a hardware issue in the controller and NOT a driver issue. It was doing much like what you describe...apparently related to side scrolling sensors. I fixed it by smacking the "pointer sensor" part of controller on the palm of my hand relatively hard, but not hard enough to where I was afraid I'd break it. It fixed the issue.
