An update...
I had register_globals turned off. Now that I've turned register_globals
on and changed my references from $HTTP_SESSION_VARS['ucAuthoUser'] to
$ucAuthoUser it works as I expect.
I'm not real happy with having register_globals on, though, and I'd like
to figure out what I was doing wrong.
Thanks for any suggestions.
