I have not followed this discussion from the beginning, but it sounds
like one o my Flmm widgets. Maybe this helps:

/** \class Flmm_Popup_Window
* A container for Menu Windows that are more complex than a menu
pulldown.
*
* The Popup Window behaves like a popup menu, but will vanish as
* soon as the user clicks outside of the menu area. This way, the
* Popup can contain a rather complex UI without the overhead of
* a full fledged dialog box.
*
* \todo add a 'popup()' function that will set all needed attributes
