IE6 v IE7 error!

Bit of a strange one this nd I’m not too sure where to start in fixing it, so any advice greatly welcomed!

have a flash news ticker which dispays a list of 10 stories and an image for the first story, all of which it gets from an xml feed. Each story is then lickable through to the full story page.

In IE7 it all displays correctly and every thing can be seen amd every thing is clickable.

In IE6 however it just displays the background colour and not text or anything, and no links are clickable.

Any ideas where I should start looking for errors or is it simply an IE6 problem?. Its still loading the xml as far as i can see as the error message is not displayed in flash saying it cannot load xml.
