Subject Re: RDP Display Size with IE and Firefox
Date Tue, 19 Jul 2016 12:04:40 GMT
Attached is what it looks like in IE.  The one that says 400_zoom is when I
zoom in at 400%.  You can see it is a Windows login screen.

The Disconnected overlay (home/reconnect/logout) works fine and is normal
size.  It is just the RDP display that is small.
