UltraVNC

I have just upgraded to V1.0.8.2, on a windows 7 computer and when I attempt to view a user, I get a logon instead. If this is by design Ultra VNC is useless, because I could RDP instead

Is there a setting that I should have so that I can interact with the user on their session.

I am having the same issue. I get an error dialog "Ctrl-alt-del require service, no permission"

Are you also getting this error.
