Are you clicking on "Database" in the bar or letting the little sub-menu drop down then clicking "Database Home"? The only "main bar" items that actually go anywhere on their own are "Home" and "Submit Info".
(Personally, I think that "Database" should not have a sub-menu and should take us straight to the DB, similar to how "Home" and "Submit Info" work now. With only one item, the sub-menu seems somewhat pointless. If/when there are multiple items under "Database", a sub-menu would be appropriate. It reminds me of an old admonition from English teachers when describing how to create an "outline"... if you have an "A", you must have a "B".)
