About the only recent even I’ve had was when I was sitting at my desk reading an article. I noticed the mouse slightly move, but I hand no hand on the mouse. I sit there watching it, not manually moving the mouse or typing on the keyboard. It really freaked me out. Turns out, my old desk pad had a slight curl towards the edge the mouse was at, and the curl would make the mouse sense movement ever so slightly. I deployed a new desk pad, and things are back to normal. Whew!
