Technically the Menu Bar is just the toolbar containing File, Edit, View, Favorites, Tools, and Help. Is that all that's disappearing, or is it the Title Bar, Menu Bar, Address Bar, and all the rest? If it's the latter try pressing F11 to toggle Full Screen Mode on/off. On the other hand, if it's the former, it sounds like IE7 may be corrupted. First, though, try selecting Menu Bar from the Tools menu and see if disabling and then re-enabling it works out the kinks.
Let us know.
I have IE 7 and the menu bar has disappeared and reappears when I move my cursor up to it. How do I go back to the original setting? I did (not to my knowledge) make this change. I am running Windows XP home SP2 on a P4 3.2GHZ.
Thanks in advance!
