Clipboard stops working

[cruvis]

The clipboard stops working completely (not just host<->guest, but on the guest itself) when a remote desktop session is established with the guest.

The clipboard on the guest can be brought back to life if the 'Shared Clipboard' is 'disabled' on the 'Devices' menu.

I am also remote-desktop'ed into the host when this problem occurs.

I can also re-establish clipboard functionality if I close then re-establish the remote-desktop session to the host.

Once I do this however, a new, worse issue arises: a subsequent attempt on any/all guest machines to 'shut down' (through the guest OS) or to 'Save the Machine State' through Virtual Box will cause the guest session to hang permanently. The only solution is to kill the Virtual Box processes in the Windows task manager (the 'save state' data is lost).
