Thanks Lloyd for the feedback. I've commented below. I'll get these into Bugzilla in one form or another and send you pointers so you can track them if you like.

This is important because with identical VIC's it isn't obvious which VIC the opened camera windows on display in a conference came from, and if one wishes to disable a camera during a conference, there is a risk that all cams on the display will disappear! 

This should only happen if you're running multiple video consumers on one machine, or a video consumer and video service; this scenario is unlikely, as there's no benefit, but there is the drawback that you mention. Video producer vics are labeled with the capture device name, and are minimized at startup by default, so they shouldn't contribute to the problem described here. If your case falls outside of these, let me know and we'll address it.

See point above.

I know we discussed problems caused by this option. It'll be reviewed for the next release. I think it's very useful functionality, so if the problems with it can be resolved, that would be the ideal way to go. 

I believe we also discussed problems with the "Open for All" option that occurs on the sharedapp context menus. It's clear why that option would be problematic, especially without options to always accept or always reject those requests (possibly with per-site options).

This is a RAT problem related to, I believe, Tcl/Tk blocking the application during GUI operations. I don't know the specifics, but it should really be a bug in the UCL trac for RAT.

> 	-	After rebooting the PC, 3.2 starts in unicast even though the preferences "use unicast" box is unticked.  Multicast unavailable remains on display in Venue client window even after "use multicast" is selected. But after closing and restarting AG, multicast available is displayed.

"Use unicast" means use unicast without regard for the state of multicast. When unchecked, the system uses multicast if it determines that multicast is working (by trying to receive data from the configured multicast detection group, see Preferences); otherwise, it falls back to unicast.

The name of the current Venue has migrated to the Venue Client title bar, so it also appears in the icon title when the VenueClient is iconified.
