Several people have asked about the strange behavior of IE within Flex. Normally this will be displayed as an object not properly updating in Flex. This is due some security setting anomalies but one can compensate for this by adding the following to your PHP code.

header(”Cache-Control: no-cache, must-revalidate”); // HTTP/1.1
header(”Expires: Mon, 26 Jul 1997 05:00:00 GMT”);
