need to modify javascript: opo up menus do not view in IE

I've created a web page which contains drop down menus. These drop down menus were created using the "Show Pop-Up Menu" behavior in Dreamweaver. I then saved the page as a Dreamweaver template and will be creating all the website pages from this template (rather, the client will be in Macromedia Contribute).

Test link I sent to the client:

http://www.designbymodus.com/NNPDF/index.html

When the client went to this web link to see how the site was coming along, everything looked great to him with one exception: when he scrolled over the buttons that had pop up menus he could not see the drop downs at all. He was using Internet Explorer 7.0

Apparently the drop downs can be viewed in Safari and Firefox, but cannot be seen in Internet Explorer 7.0, and possibly other browsers. I do not know how to play with the javascript coding to fix this. I know that this particular Dreamweaver behavior has had many problems in the past with browsers and other issues, but these drop downs are very lengthy and there are quite a few, so it is a very convenient way to handle them.

I would appreciate any help at all you might have.

javascript is not java.In fact, other than a few initialsimilarities, the language featuresand libraries are completely different.This is a Java forum.Please ask your question on a javascript forum.
