If that code is not executed in the same request as code that calls
session_start(), then you will have problems (though that doesn't appear to
be the case).
Try adding a call to session_start() just before that code is run, see if
that helps at all.
Is there any chance that you could send me all of this? It would be a lot
easier for me to help you if you could.

Ah, it's actually not... here's the breakdown of the
included files:
index.php (sample "normal" page which has the login
box in it)
(included at start of index.php)
-page_init.php
(included at start of page_init.php)
-dbconnect.php //connects database
-startsession.php //CALLS SESSION_START() and
contains object-like fns for session handling
-header.php (included after page_init.php. DOES NOT
call session_start as it's already called in
page_init.php's included startsession.php page.
Contains all of the jquery/ajax which you mentioned
below, and all HTML header stuff)
