Drop down menus on gnome panel broken after Hardy upgrade

[junk123]

Upgraded from Gutsy to Hardy and after logging in none of the menus on the gnome panel work. When I click Applications, Places, or System they highlight but no drop down appears. If I launch Firefox from the terminal it will open but the menus in there do not work either for file, edit, view, etc. It seems to be a global drop down menu problem but I don't know specifically which package is causing the issue.

I killed compiz and that restored my menus but now things are messed up because compiz isn't running so it has something to do with that.

https://bugs.launchpad.net/ubuntu/+source/gnome-main-menu/+bug/326756, please see my problem here too. I resolved mine by re-installing and redoing my home partition (getting rid of my settings).

I'm going to mark this as a duplicate of bug 326756 because there is no other reports of this occuring due to compiz. It may have been restarting any window manager would fix the problem. Please re-open if this there is any evidence to show this is not true.
