I am using the beta 1.0.7D, and for some reason the CAP lock button is stuck on and I cannot turn it off. Pressing the caps lock button on my keyboard does not turn it off in the session. In order to log into my remote machines I need to use the shift key to alternate the stuck cap button.
At other times, the Mac CMD button (which maps to the Windows button) gets stuck on. When this happens, I cannot do anything, because when I press the letter "r", it turns into Windows+r, which brings up the "Run..." window. Pressing "L" will lock the computer, etc.
I only see this on RDP sessions (Windows 7 and 2008 sessions).
