When I click on the "assorted examples" link, it pops up a dialog to ask me if I want to leave the page. After I tell it that yes, I really meant to click on the link that it had offered me, it displays the examples... and promptly replaces them with an empty page after a few seconds. That annoying dialog also comes out when doing other things, like using the Back button.
