Hey all. I bought a Logitech LX7 Mouse off of ebay. I have installed the drivers for it as well as Logitech setpoint. Setpoint recognises the mouse as well as windows. However when i move the mouse, it doesnt move on the screen. I know that the mouse laser is working because the Invisible Optic light turns off when the mouse is moved. Could this b a fault in the mouse or connector? Or should i return this mouse? Thanx 4 any help!
