<HTML>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 ? </HTML>
