First of All I'm using Ubuntu 13.04 and I don't remember this problem has ever been produced by the previous releases.
Unity Global Menu Integration is missing not for all the applications but some of them. Here it is the programs that can't integrate with Unity Global Menu:
- Software Center
- Archive Manager
- Adobe Reader
- Document Viewer
Some programs can still integrate their menus with the global menu, such as Firefox and File Manager.
I want The Global Menu Integration back.
Thanks in advance.
