Thank you for the information. What you describe looks exactly like how RDP mode works. Are sure it's Remote Utilities' own Full Control mode that you are using?
it should be noted that whenever you experience any connectivity issues your only reliable source of information is the log, or more specifically two logs - Viewer's and Host's. Without the logs it is just guesswork.
Lee, we will notify you about it in this thread. Besides, once Microsoft does its part they should update their records accordingly and this problem should be fixed.
