[jQuery] document.ready fires too late in IE


Hi,
I'm using jQuery's document.ready in a page with some external iframes
(ads). In IE 6 & 7 document.ready fires when all iframes are
loaded ,while on other browser the event starts after loading of the
parent site is finished.
Is this a known issue, any hint how to avoid this behavior in IE?
Best regards
aj
