I've had my Logitech VX Nano for roughly about 2.5 years and recently its been lagging quite a bit. When I move the mouse around the cursor doesn't seem be move as smoothly around the screen. Sometimes when I click on something it does not register the click until I click it multiple times. The weirdest thing is it doesn't always lag, sometimes its fine sometimes its awful. Things I've tried: - Reinstalling driver and setpoint (no luck) - Tried a different mouse on my computer (seems to be fine) - White surface (still lags) - Tried 2 sets of new batteries (no luck) Anyone got any idea whats wrong? Also is this mouse suppose to not work on a completely black surface?
