I had been experiencing jumpy mouse pointer movement with a Logitech MX700 optical mouse and an LX7 laser mouse. Logitech Support Answer ID 29 described that a black or wood grain surface could cause erratic mouse pointer movement. Those are the surfaces that I have. This is a link to the support document.[...]I chose the silver Fellowes Microban mousepad (model 5934001) for its higher reflectivity. It measures 3/32-in (3mm) thick by 9-in (23cm) wide by 8-in (20cm)deep. The thinness of this pad is useful for fitting over the integrated black mousepad on a keyboard tray. I chose the pricier Microban product because surfaces do get a bit grimy around my workstation.
