Yeah, I HATE this one too! I want 3.6 back. It took away my Norton 360 Identity tool bar so I have to look up my passwords every time I use a passworded site. It's a royal pain. I should have known better than to upgrade. It's always worse in most every program. For crying out bells, leave things alone!

go back to 3.6 or use a theme to make it look how you want it to.
