Hey guys, my 3 year old Razer diamondback mouse wheel won't scroll anymore (wheel click works fine). It was working fine a few hours ago but then I felt a click as I was scrolling and then it just stopped working. I opened up the mouse and everything looks fine. The axle is intact and turns the gear fine. I even took the wheel and axle out and tried turning the gear by hand but that still didn't work. Is it time for me to get a new mouse?
