[TYPO3] I loss the "right-click" menus

[henri delebecque]

  Hi Dimitri,

Thanks four your help.

I have tried that, without success.
Moreover, I have actually the two versions of the cms running (the 
good and the bad one), used with the same browser, the good one with 
the right-click menus, and the other one without.

I think that this behaviur is not compatible with a client-side 
problem, or I miss something ?
Best regards
