note 24219 added to function.session-start

I've noticed that when i start up a session to control access to my site the session does not get destroyed with the closing of the browser. I have a logout button that can destroy the session but not many people remember to log out. Does anybody have this problem or know how to fix it? -- http://www.php.net/manual/en/function.session-start.php http://master.php.net/manage/user-notes.php?action=edit+24219 http://master.php.net/manage/user-notes.php?action=delete+24219 http://master.php.net/manage/user-notes.php?action=reject+24219
