We have a user with a Surface Pro 4 that will be working away and then another program will open or it will go to Task View. Before that happens, it's not like you can see the mouse move over to that spot and then it opens, it just all of a sudden happens. She did have a wireless keyboard/mouse so I hooked up a wired mouse to make sure there was no interference and it still happened. I've run a number of scans to make sure there is no malware and it hasn't found anything. Any other suggestions?
