Thanks for the reply, Rich, but unfortunately the dependency for the current available Remmina is FreeRDP 0.8.2, so even if you add FreeRDP 1.0.1 (which I have done) Remmina does not make use of it. You can force FreeRDP 1.0.1 by way of the command line, but that does not solve the problem for us.
Looks like Remmina 1.0 has be out since Feb. 2012, so I imagine it should show up soon, I hope.
