All Levels Navigational Menu v3.0 - first line disappears on # click

1) Script Title: All Levels Navigational Menu v3.0

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...menu/index.htm

3) Describe problem: The first item on the first submenu disappears when you click on an empty link button in the topbar.

How to replicate this problem:

1. remove links on topbar buttons and insert a generic # on the links.
For example: <li><a href="#" rel="ddsubmenu2">CSS</a></li>

2. click on this button: the first item of the firs submenu disappears.

I would like to remove any link from the topbar, without losing submenus if visitors click on the topbar.
