That's exactly what I had thought when reading this. To Marty: please try again with Fl_Group, because Fl_Pack won't do what you want, unless you use Fl::add_timeout() for the popup. Besides looking at the correct bounding box issue, you must only calculate the new button coordinates after changing children inside the group. Only if you want predictable resizing behavior, then you must also call init_sizes() after rearranging children. That should really be easy to implement...
