When I click a link, it shows the URL without a Forward button. If I click the Back button, the Forward button appears and pushes everything over. When I click Forward, the Forward button is grayed out, but as soon as I move my cursor away, it disappears and again looks like the first.
That would explain it :) A similar effect happens with the Stop and Refresh buttons. If you put them next to each other, they become a single element. And if you put them both at the end of the address bar, they all merge together. But if you move them apart, they are separate buttons.
