I'm using Ubuntu Classic in 11.04.

When Firefox and Pidgin are maximized, and I change tabs, the titlebar does not change as it should to reflect the current tab. Unmaximized, the title will update normally.

I've gone the route of suspecting the global menu from Unity, and I've uninstalled firefox-globalmenu and indicator-appmenu, but so far the problem still persists.

Any ideas?
