Sorry, I can't really help you more. I don't have FLTK 2.0 installed.
However, I'd suggest that you also resize your sidebar in showCB:
void showCB(fltk::Widget *w, void *g)
{
((fltk::Group *)g)->show();
((fltk::Group *)g)->resize(0,0,95,win->h(); // *** added ***
bigbox->resize( 95, 25, win->w()-95, bigbox->h());
rbox->resize( 95, 150, rbox->w()-95, rbox->h());
win->init_sizes();
}
Maybe someone else with FLTK 2.0 can help.
