[gnome-flashback] Button "File" desappears in some windows.

[Luca Della Ghezza <luca_dgh yahoo it>]

I recently upgraded from 12.04 to 14.04 Gnome Flashback, I have 2 users. In User 1 some windows like SimpleScan or Mahjiongg doesn't have the menu bar where there are some buttons like "File" (or other names for that button). The strange thing is that in User 2 the same windows have that bar.
I attach 2 screenshots to explain better the problem.
How can I have that bar in User 1?
I tried to surf dconf, but I found nothing.
Thx a lot for your help.
