It's a one threaded application. Calling fltk::flush() right after the deletion doesn't change anything. I wonder why simple redraw() or relayout() doesn't help in this case. It's just when a user clicks on a button I delete the focused child of a PackedGroup. Like already explained, this way doesn't work either:
