facebook php application frame issue

[mforan]

For some reason, in my application (http://apps.facebook.com/ambroid/) when the page is loaded in IE, the frames jump out of the facebook iframe and into a full screen.

this doesnt happen untill the user has logged into their account or created one. On the first login page/create there is no frames this problem does not happen on the page.

 

What i dont understand is why in firefox or chrome this problem does not happen. Is there any reason behind this?

 

the frames for the game are pushed out using:

<?php
echo '
<frameset cols="130,*" noresize border=0>
<frame src="nav.php?isface=1" name="nav">
<frame src="hq.php?isface=1" name="main">
</frameset>';
?>

the problem only occurs in IE, any ideas peoples?
