I have been trying to puzzle out just a little mystery now for some time, however i cannot appear to discover the issue. This Wordpress blog, which I am controlling, has this really annoying left-over pixels around the right making the scroll-bar appear unnecessarily.

Does anybody know what's leading to this, and/or how you can repair it? Thanks.

You've got a border round the ul#suckerfishnav - pull it in the right and left sides because it adds 2px for your layout.
