My colleague and I use SC to work over distance. Really nice tool for that. I'm on Ubuntu 10.10 and he has Windows 7 (or probably Vista).
Streaming my desktop to him works like a charm. Unfortunately the other way around, the images freeze after a while (ca.3-5 min)
I have the impression that this depends on the amount of data transfered. So if there is a lot of scolling, changing windows etc. it freezes earlier. It probably gets out of sync grabbing the Windows screen and can't catch up again.
How would one try to analyze this?
