Let me start off by saying I am not the person who usually edits our company's wordpress site.
With that being said, My user is having problems with the 'Home' navigation links for a modified Twenty Ten template. None of the child links will show up under it.
Instead, they show up as parent links at the end of the real navigation links.
All of the other navigation links that have child links hover down just fine.
I've changed the child page numbers as well as made sure they were all attributed to the 'Home' parent.
