Navtab Question

[Dirks]

I did some research on the forum, but wasn't able to find much on point. Maybe you guys can help?

I'm trying to add a new navtab that simply changes the default links under the tab rather than opening to a new page. However, when I leave the target URL link blank, clicking the tab defaults to /index.php. It will work properly when I add menus, but not simply links. Am I missing something, or is this beyond the scope of the built in navigation manager.

Alas, I'm not on a computer where I can snap screen shots, but here's the tab URL to poke around: http://www.althanas.com/world/?tabid=157

Thanks!
