Ok so my mouse has been going really slow lately, it stutters on the screen (stops for like half a second, and then continues) every so often, and it just been super slow. It never does this when i put it on a different surface (ex: the top of my computer) But it goes super slow on my mousepad. (theres nothing wrong with it though because i used it before and it worked just fine. Its a wireless usb mouse by logitech. Also i installed the windows update for it
