I'm using the Remote Desktop Connection Manager 2.7 on a Surface Pro 4 with Windows 10. Until recently, it was working fine: It would go to full screen and show this blue full screen connection bar at the top when pointing there with the mouse. I could close the session from there or leave full screen mode.
A few days ago (no idea what happened), it stopped going to full screen properly. Now it only resizes to the full size of my screen minus the task bar (so I still see that and the RDCman's window is also not behind my local task bar. The blue bar at the top appears for a moment but I cannot get it back when moving the mouse there.
Reinstalling did not help. Any idea what might have caused this and how to fix it?
