One thing I'm noticing, is that sometimes, Remmina will indeed sustain multipl RDP sessions, but only one of them will be accessible at a time.
For example, I just connected to 2 different windows machines. As, soon as I connected to the 2nd one, the first one's session was not accessible by either "alt-tab" or "by clicking twice onto the Remmina icon on the Unity Task Bar"; when I click on the Remmina-task-bar-icon (twice), instead of showing all sessions I have open, it only shows the Remmina client manager itself and the 2nd session I launched. If I then log out of that 2nd session, the first session is accessible as though it never dropped.
