thanks your rely.
the screenshot is in attachment.
the menu is missiong. even if reinstall.  I remember the last operation is change same params in menu "setting" . so I think  those params is store  somewhere in computer. but  uninstall can't remove those setting params , it lead to reinstall is invalide.

Have you tried to put you mouse over the top bar?
And I don't think C::B has any control on the menu, for sure we have no options to show/hide it, it is something in ubuntu's unity.
