element's z-index value can not overcome the iframe content's one

Question

I have a div and an iframe on the page the div has

z-index: 0;

the iframe has its content with a popup having a z-index of 1000

z-index: 1000;

However, the div still overshadows the popup in IE (but works fine in Firefox).

Does anyone know what I can do?
