Hey guys,

I've got a GX850 that's no longer moving the pointer (but the Mouse click buttons seem to be working) so I figured that the sensor might be broke or require cleaning. However, what throws me off is that the DPI button, when pressed, doesn't seem to toggle the DPI on the driver anymore. Tried using the mouse on several systems including a Mac so I don't reckon driver could be an issue? Anyone can give any suggestions on what I should try out?
