I'm using a Surface Pro 3 with multiple monitors... This morning windows 8.1 updated itself and I've had issues with the mouse ever since... Initially the mouse pointer disappeared, I could see it highlight what I was hovering over, but the actual pointer wasn't there. Apparently the fix for this is to restart the surface and rather than swiping up to login, click with the mouse. This seemed to have worked. The issue I have now is that the mouse pointer stick in a screen unless I hit the boundary of the screen moving fast. This is a nightmare! I had a quick google of the issue and some guys were changing registry files, but this can't be the solution? Does anyone know how to put this back how it was?
