When I type in a question title and tab out of that textbox, the Related Questions box appears, but not in the right place. It seems to be offset several pixels up and to the right, and overlaps with the title textbox.
My hunch is that this is some kind of CSS float/clear screwiness. I'd investigate it myself but at least half of my gray hair is due to trying to fix exactly these kinds of issues on other websites, and I don't think I'd be able to live through that pain again.
It's pretty noticeable, even without the giant arrow. Fix it please?
Edit: Forgot to mention, this occurs on Firefox 3.6.10.
