Simple positioning problem between index.php and pages.php

Hey all,

I am getting ready to launch a blog I have created but there is a small problem between the pages using index.php and pages.php ie: my dynamic and static pages.

If you look at https://www.georgehajian.co.nz/wordpress/ you can see that when you move from the Home or Resume page to the Weblog or Art pages the page shifts a little to the left.

I have been over and over the the site’s CSS with Firebug and can’t find any specific CSS used in different pages that may cause the problem. The blog is centered too, so theoritically it should always be in the center, and as far I can tell my page widths are the same across index.php and pages.php.

Any ideas?
