add these two simple cases to give dragging feedback:
case FL_ENTER:
window()->cursor(FL_CURSOR_NWSE);
return 1;
case FL_LEAVE:
window()->cursor(FL_CURSOR_ARROW); // or FL_CURSOR_DEFAULT or ?
return 1;

But don't drag one of the buttons out of the window and release the button.
That's one of the cases that need tidying, isn't it? ;-)
