I don't know if this is the right place to report any bug, so please tell me if I'm wrong.
I'm running Linux Mint 12 (uname -a : Linux mint 3.0.0-15-generic #26-Ubuntu SMP Fri Jan 20 17:23:00 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux).
Popup-menu can't be clicked and window menus won't show.
I have to use keyboard direction keys to navigate through the menu then press ENTER.
Thank you !
