Excellent -- I think running without authuser.php is better in general.  So,
that's one less thing to worry about.

I'm pretty sure you're seeing the browser's cached version of the page,
before the logout occurred.  On the server $isEditAuthorized is certainly

Aha, this is very likely the issue.  ?action=logout is issuing the redirect,
and the browser thinks it already has the page in its cache and displays
that one (i.e., the one before the logout).  Try turning $EnableIMSCaching 
off and see if the $isEditAuthorized appears correctly.  If that works, 
then maybe we can find a way to get ?action=logout to work with IMS caching.

Also, what browser are you using?  Both IE and Mozilla/Firefox have their
own little caching quirks.
