I have a Optiplex 9020 computer and it was upgraded to Windows 10. Now when the user is typing or working in any program her open programs will vanish. You can see a ghost outline of the box and if you wiggle the mouse they will come back. We have dual monitors hooked up and this happens to both screens. I have checked that we have all the latest updates. This is not happening to anyone else who was upgraded to Windows 10 and use the same programs.
