Bill,
I was trying to do the same thing and just ran across your post. Here’s the simple solution I discovered:
On the Menu page of your WordPress 3.0 Dashboard, create a custom link with the URL “#”. Don’t use http:// or anything else in the box, just the hash sign. Label the Menu Item, add it to the menu and then add whatever submenus you want under this menu item.
Hope this helps.
Tony
