Eddie,

It sounds to me like you may have an issue with your sessions, as 
presumably the php download script is blocking your other pages from 
accessing the session.

If you put a call to session_write_close 
(http://www.php.net/session_write_close) after anything that needs 
access to the session but before the portion of the script that takes a 
long time, it should fix your problem.
