I was using Windows 8 the other day and noticed that there is now a second cursor image (arrow) at the top left of my screen. It doesn't move, it doesn't do anything really, except sometimes go busy if the window below it is loading something.
My regular mouse cursor works as it should and moves when I move my mouse. I checked device manager, but it doesn't think that there's another mouse attached to the computer. It stayed after I rebooted my machine.
What should I do? Should I leave it there and see if it grows? Feed it cheese? Perhaps wiggle the other mouse and see if I can scare it away?
