However, there shouldn't be any messages like "Current session on hold". Are you sure you are using Remote Utilities' own Full Control mode, and not the RDP mode?
Well that's sort of the problem, I don't get messages it's paused. Therefor I was looking all the time why my session had stopped suddenly. It didn't respond and gave no messages why.
After a few month searching within your forum, faq and RU-client I found it was "put the current session on hold". First I thought it was a connection problem or some program freeze... And therefor I was restarting my client all the time.
Can you make this feature optional?
