So what are subwindows good for when the panel library does exactly the
same thing with less flashing? I thought that the panel library must be
used with overlapping windows and that subwin and derwin on the other
hand could be used so long as every window overlaps with nothing but
stdscr. What is the truth here? When is it that subwindows should be
used as opposed to the panel library then?

Thanks,
