These directories were all attempts
to figure out why the javascript demo
in the "fails" directory wasn't working
under internet explorer 6 or 7.

Turns out the problem is a "gotcha" 
with IE's javascript/DOM implementation, 
which is mentioned here :

  http://codingforums.com/showthread.php?t=8408

namely 

 " IE exposes document.all on top of the window object as well.
   document.all.bla == document.all('bla') == document.all['bla'] 
                    == window.bla == bla;
 "

so therefore anything like

  something = document.getElementById("something")

can produce problems under IE.

Also mentioned in passing at 
http://developer.novell.com/wiki/index.php/Manipulate_the_HTML_DOM

  "Note: You should not use variable names that are the 
   same as the id of HTML elements in your page or 
   IE complains and fails to work properly."
