Here is a functional example of drawing dynamic windows and refreshing them using ncurses_wrefresh.
This draws the main window, borders it, creates a small window borders it, creates a lower window
and borders it as well. it also shows an example of doing a little backgrounding..
<?php
/*
the window will look somewhat like this...
+--------------------------------------+
