My cursor has a mind of its own. I don't use a mouse, but I use the mouse pad on my surface. The cursor just moves up on the screen till it hits the top and then stops. When I try to move it with the mouse pad, it won't even stop for me to click on something...it just keeps moving up. Is there a setting or something I need to change to get this to stop? It literally JUST starting doing this but is very annoying because I can't click on anything I need to. Please help! Thanks
