This is a strange thing that just recently started happening. When I remote into a computer that happens to be running a remote desktop connection to one of my servers, I can usually see the remote desktop connection bar at the top of the screen in my RVNC session. Lately, however, this connection bar is invisible. It's still there because I can ask the computer user to minimize their RD session, but I cannot see it in my VNC session.
Like I said, this only just recently started and is most likely the result of a MS update of some kind. But I would like to know if and how I can make this bar visible again.
