for some days now I have been experiencing a problem when connecting to a rdp host. Desktop size is set to manual at 1152x864, resize mode "None", open in external window. When I start the connection the rdp window is shown within a small window with scrollbars, although the desktop size is much smaller than my physical desktop.
When changing Resize Mode to "Smart Reconnect" the initial window is even smaller, only after moving the rdp window it will get resized to the configured desktop size.
My environment: Windows Server 2008R2, Ati 3870, 2 displays 1280x1024
