view story

http://askubuntu.com – the top bar which includes File, Edit , View is missing in Gnome Classic on Ubuntu 12.04 . On switching to Unity and normal Gnome 3 , the top bar was usually merged with the Menu Bar , akin to Mac OS interface . However, I am using the Gnome classic version , can anybody tell me how to enable the top bar of applications . Thanks . (HowTos)
