Partial remote control I'm hitting the same 'freezing' problem.
I'm frozen, varies by what I try to do. Even if I ask the end user to do something, I do not get the function back to do anything? All I can do is END the session on the top bar and reconnect. If there is a UAC prompt happening, I can't see it, and possibly the client end didn't see it either, not sure.
I'll assume this is a QuickSupport problem?
What I had to do was reconnect (after the 3rd time) and install another Remote Desktop program on my next connection. Prefer Remote Desktop though.
I didn't think of running the Quick client in Administrator mode? Will this be a via able workaround? Either I could do it on a connect and then reconnect telling the user to close it and reopen it?
