document.ready firing too early within iframe

Hi
Im trying out the new document ready code from SVN.
I am finding that when my page is within an iframe, document ready
fires at the wrong point in IE7.
IE6 and firefox work fine. IE7 worked ok with the old document ready
code (e.g. 1.2)
Any ideas how to fix this
Sorry for the lack of punctuation im writing this on a danish
keyboard !!
