If you are using tabview, you shouldn't be putting the tabs on each of the pages. Tabview transcludes the pages in the tabs. You should have a main page and put the tabview on that page only. When users switch tabs, they are kept on the main page. The reason the Simpson's Wiki does it without tabview is because it grants them greater creative control over the tab styles. However, this necessitates that, rather than using true tabs, they actually use links to the subpages.
