I've recently installed IE7 and when I ran it I couldn't see the address bar and some of the buttons. I was going crazy trying to find the solution: I thought it could be the theme I was using, I thought there may have been a problem with my Windows key...
in the end it turned out to be object bar.
if you're experiencing the same problem, go to object bar properties -> file -> general options. in the 'general options' window make sure that the checkbox next to '...and hide moveable menus from explorer and IE windows'.
this solved the problem for me.
hope this was helpful.
