logo center radio button does not work

CBOX member Greg Acuna noticed that the logo positioning radio buttons are not working correctly. I tested on my site and notice the same. Here is a link to the thread -

I can confirm that this occurs too. Any fix for this is complicated by the position: absolute declaration on the anchor and the attempt to centre the logo using left: 50%. This fails because the enclosing hN element has zero width. I'll see if I can come up with a solution.
