Main content overlaps hovering navigation on IE

[mps]

First off, the site in question is http://74.92.11.124.

If you open the site in Internet Explorer (6 or 7) and try to use the navigation system, the popup submenu is not visible. The main content of the site is overlapping it. It works fine in most other browsers.

I have already tried searching this forum for similar issues but to no avail.

Any help would be much appreciated.

Update: Got the problem fixed - we had to adjust the z-index of the divs that encompassed the unordered list.

In udm-custom.php, you may need to set the z order variable to a higher number. This is in the array $um['orientation'] and is the last variable in the list. See if changing that solves your problem.

Hmm, increasing it from 1000 to 10000 did not solve the issue (it seemed to not have any affect whatsoever). Any other suggestions?
