[jQuery] Help with weird IE z-index using jquery corners and perciformes menu


Hi,
I'm building a small site and using Dave Methvins jquery corners to
style the dives and just added the perciformes menu (jquery
suckerfish).
The menu works well in various browsers but in IE the expanded menu
sits behind 2 "cornered" divs.
I tried adding the bgiframe plugin to the ul of the submenu and
explicitly setting the z-index of both the nav ul and the divs
covering it but nothing seems to make a difference.. help..please...
The site is at http://mfusion.com.au/telechase/signup.php
