Yes, I think it must be something like you suggest... I can certainly
add a defensive check as you suggest and see if that helps: I'll do that
later today, I hope.
The tool palette's are Fl_Double_Windows filled with lots of little
(Fl_Box derived) widgets, so I was expecting that the "active" widget
would be derived from Fl_Box and would have a parent window, though...
