Hi,
In my listbox I've defined as doubleclick-event the opening of a popup-menu.
It works very well, the popup-menu appears perfectly, but its callback does 
nothing ...
I wanted to do something depending of the selection done before in the 
listbox but when I selects an item in the popup-menu, nothing, it disapeared 
just as if the action was done but in fact it does nothing.
(the callback action works, I use it for another button)
Does anybody know why ?
