When you run the mouse across this link, the title appears at the very top of the screen, across the entire width, and has up/down arrows in the middle (not that you can reach them). Also it will at times overwrite the sidebar with a rectangle of yellow (same height as the title box) - this doesn't always happen with the small example; the full example shows it consistently (the GEForce GTS link in the lower-right column)). The overwrite goes away when the Title goes away if you move the mouse off the link.
