Thanks for the response. A new data point we ran into today, trying to paste with a ctrl-v resulted in the application we were using on the RDP host bringing up the 'open file' dialog, and it did it repeatably. I think I need to dig more into how all of this works, it's almost as if the ctrl sequence is sending the wrong keymap - inserting a ctrl-o for some reason. The ctrl-alt-shift works, but has been deemed too user unfriendly, unfortunately. A good sanity check, but not going to cut it for the final application. I know these clues aren't well-formed, I'm just hoping some of these symptoms ring a bell for someone out there.
