Since updating OS I seem to have lost my settings for beta invitation so can't now see the user that has installed invitation application on PC when starting webcam on N800 (Even though restored all my settings via a 12mb backup) (No grey/green user icon, however can see other normal gmail users)

I also had problem in previous OS release where webcam would not work from PC to N800, assumed it was a limitation of the beta invitation?
(Only worked from N800 to PC unless N800's were used at either end?)
