This really isn't the way to do this - you can't properly update a
widget whilst you are in a callback, since the display update processing
waits untill all your callbacks return, to minimise redrawing, but your
callback does not return, and you have built in hard coded (and
non-portable, I notice) delays inside your callback.
You might be able to trick it into working by calling Fl::check();
before each sleep() call, but that would constitute a nasty hack.
Rather, you should use your callback to start a timeout (see
Fl::add_timeout) and have the timeout update the output widget each time
it "ticks". Your timeout would of course expire itself after the last
screen was shown.
