Comment box is not at the right position

Hi, I currently have a problem with the Catch Box free version. The Comment box is not at the right position. The comment box is a little bit on the left side of the real one. At the beginning of loading the site it is on the right position but after completely loading the site, it moves a little to the left. Here is my site www.icecreamhunter.com http://www.icecreamhunter.com/fiction/longsword-chronicles/
