I had just gotten off the phone with tech support so all of my programs were closed showing only my screen saver. Movement caught my eye from across the room, programs were being opened. I tried to control it and close all the programs but my cursor was being held captive. I had to unplug the machine to get it to stop. I got in touch w/ tech support, they said it wasn't from their end. Has anyone had this happen? What does it mean? What can I do about it?
