[SOLVED] Pages Submenu Not Showing

Wordpress 2.9.2
Atahualpa 3.4.6

I have added 2 new pages with a blank parent page. The dropdown submenu is not showing when the parent page is highlighted in the menu bar. I know that I've done something boneheaded here, because when I put the first page in that referenced the parent page, the submenu was showing. Now it's not............

Any ideas?

Thanks,
