Is the Toolbar PageRank indicator compatible with IE7 tabs?

[petehall]

I have the Google toolbar installed on every PC here at work.

I know the PageRank indicator is supposedly useless etc, however I use it quite a lot.

For instance I won't order online via a site with no PageRank - so accurate or not, I do feel it has it's uses.

Anyway I recently installed IE7 on a machine for testing and have noticed the the Google PageRank toolbar isn't compatible with tabs?!

If you open a new browser tab then the PageRank bar remains grey. Or is this just my machine?

Can anyone else confirm this to be the case?
