Please note: If you already edited your phpgwapi/inc/functions.inc.php to switch it off, you will get an cvs conflict on updating, just do a "cvs update -C phpgwapi/inc/functions.inc.php" to fix it. If you want to use the session restore or you already used it, you need to go to Setup >> Headeradmin and switch it on there.
