nautilus global menu failed to open after live session started

[Nicola Corti]

As soon as Edubuntu live session start, desktop global menu' doesn't work, I can see the menu names but I can't click on it.

If I start an application, then globalmenu begin to works, even if I try to click again on desktop globalmenu.
