I am also running into issues with very slow connections and locking up. It seem to happen with several of my connections after the last video conf. upgrade. I am unsure if it is a bandwidth issue or an application problem.
Please help.

It really looks like some kind of connection issue, could you please provide a bit more details on how this happens. Or if you can reproduce this scenario please send us the Diagnostic Info from the Main Menu right after this lock-up happens. Please mention this forum post in the description. Thank you.
