It's awesome that the "middle-click" can move RDC window in full-screen mode. However, it would be better if there is an option that limit the move between two monitors.
For me, the problem is serious, because I have a monitor that is set to vertical, and the RDC window is re-sized each time after moved to the monitor. I hope I can just move the RDC window between my two horizontal monitors by clicking mouse middle button.

Thanks!
