CSS Problem--probably with clearing divs

This is specifically NOT a problem with PunBB, but in its integration with my rather complex layout. I consider myself fairly handy with CSS, but I'm having trouble tracking down the source of this issue I'm having, so another set of eyes would be extremely appreciated.

My PunBB install lives at http://hellbox.org/sb/boards/

The problem is this: in my lefthand column I have a sticky-note looking field for displaying information that can be seen on every page of the blog. When you're logged in (which you can do so with the temporary log/pass: test/test--although I ask that nobody post with that login, if they are inclined to) the "punwrap" div extends to the bottom of the yellow box, which makes the punwrap div ridiculously tall.

I've tracked the problem down to the <pun_status> block of code, and likely the <div class="clearer"></div>--but any monkeying I've done with it has made the situation worse.

So, if anybody has any ideas, I'd love to hear them. If I stumble across a fix on my own (which, ideally, I'd like to do without modifying the static files) I'll post it here.

Thanks very much, and thanks Rickard for such amazing software. I've used other BB systems, and this is by far my favorite.
