<g>  I see.  That makes more sense (ouch).

Yes, but he was testing stuff for me to make sure that the examples for
my book work on other systems than what I've got ready access to.  Even
if M$ users are limited to only one visual, winfo_visualsavailable()
should return that single visual properly.  Not puke on people's shoes.

It looks like the TCL call is returning a string instead of a tuple, so
the parse() call is expecting the tuple and pukes.  It would really be
nice if it just worked.

As it is, I have to wrap the call to winfo_visualsavailable() in a
try:except or test the OS first.  Either way, it's excess code that
shouldn't have to be there.
