The Scroll On My Touchpad Has Stopped Working
I took my computer in for repair when it would not turn on and eventually I was given a new motherboard. When it came back I was unable to scroll using double fingers on the touchpad. Is this because it is no longer possible or can I adjust some settings somewhere?
