For months the Google bar has been working fine and provided PR all the time. Now it has stopped!
I have tried turning off firewall, clearing temp internet files, reinstalling the bar several times. Is there anything else I can do to try to get the PR feature working again? Or is it no longer supported?
I posted with the same problem about a month ago (http://www.webmasterworld.com/forum80/518.htm) - no responses that restored functionality for me, although I did get stickies from other members looking for solutions.
For what it is worth, after about six weeks without working, my toolbar suddenly started providing PR again, although not on all pages of all sites. It is really weird.
