When ever I go from a page or a post to my static frontpage the whole container/layout always nugdes or jumps some 10px to the right, and I cannot understand what would be causing it. I don't see anything that should be moving it.
Whenever I go from one post to the other or any other page, nothing happens.
Front Page:

Post Page:

You can see that the left edge of the container has moved slightly to the left, compared to the post page, as seen in the head of the arrow.
FYI: ATA 3.6.4 and WP 3.1.3
