Originally posted by Bad wolfThird edit's the charm. I've got it pinned down now. Here's the deal. In the

case of the "buttons" above they've linked the entire divs (layers)
containing the button text. If you activate (hold your mouse down on) any
other links (like the profile link next to each post) you'll see a border
appear around it. This is default rendering of active links in firefox.
Now, a link usually contain text, so the browser will put a border around the
textual content of the link. For some reason, the border collapses into a
single dot when the contents of the link is not text, but a div-tag. This
can be styled away, but it's not a big issue performance wise.
