Used to be that when you clicked on a menu tab it was the same as selecting the first option on the list. So in the Board Games database, Clicking on the "My Geek" tab does indeed open the "Profile" option. But clicking on "Help" opens another window of whatever you're viewing (at east in FF).
Clicking on the tabs is odd. I can't think of another program that works this way. So either do away with clicking on tabs or make the feeeeature consistent.
