Superfish problem: doesn't work in IE6 and IE7

[outre99]

Hi all,

The Superfish drop down menu is not working in IE6 and IE7 but in
different ways.
In IE6 nothing woks.  No dropdowns show up.

In IE7 the dropdown menu is hiding behind the content div even though
the Z-index has been increased a great deal.


You can see it here:  http://pangu.arctosgroup.com

As usual all of the other browsers work just fine.

Any ideas would be greatly appreciated.
