Added a sample to the demo showing how to change the cursor, what all

#
# o Updated for wx namespace
# 
# 11/30/2003 - Jeff Grimmett (grimmtooth@softhome.net)
#
# o Some issues with the listbox example; I tried correcting
#   it but it's still not working the way it should. Commented
#   out for now but will be revisited.
# o The math in determining the popup window's position is
#   a bit off.
