RDP logoff bug

We're in the process of evaluating RDM (pretty sweet so far) and think we've come across an RDP bug. After creating and connecting to an RDP session, if you hit the 'LogOff' button in the RDM ribbon, it appears to be sending the wrong command to the RDP session. It's sending 'ashutdown /l' instead of 'shutdown /l'. It does this in both the Free and Enterprise Trial version.

Is there anywhere we can change this in the client, or does that have to get resolved in an update?

Thanks.
