Drop-down menus don't work properly.

I love the appearance of Quicksilver. Thanks for it. I've installed it - correctly, I think - and my Primary links do indeed appear and function properly, but the drop-down menus are not working right. The menu items that have sub-items (i.e., those that should have a sub-menu) do not have a sub-menu unless I am currently viewing that page.

In other words, when I load the main page, no menus have sub-menus. But when I click on one of the menu items that have a sub-menu and that page loads, then only that menu item has a sub-menu.

You can view this happening here.

I've seen your menu system working fine on all the demos on Agileware's website, so I know your menu system works fine. I must be doing something wrong, but I can't figure it out. Ugh!

Thanks for any help you can offer.
