Re: top menu bar missing
If you are logged in to Ubuntu, or to Ubuntu 2D. all Window menu bars for the active Window, are displayed in the top bar - Global Menu - accessed by placing the mouse cursor on the top bar.
That's normal in Unity for 11.10.
Edit: If you want the previous display the easy way is to log-in to Gnome Classic, but you may need to install Gnome session fallback to get that option. Look for Gnome Session Manager sub titled 'gnome-session-fallback' in the Ubuntu Software center.

Reason: note added
"Better Solutions may bring Worsened Problems": After Lao Tse, b. circa 405BC. a contemporary of Confucius, who died circa 600BC.
They did things differently in those days, apparently!!
