Can’t remove Page Title in Elegant Grunnge on Firefox

I have a strange problem with the Elegant Grunge theme. I love the theme and have mod’d the graphics a bit, but I have the strangest problem when I try and remove the Title from each individual page. I have tried removing and simply remarking the line that generates the Page Title on each page.

<h2><?php the_title(); ?></h2>

However, whenever I do that, Firefox leaves a blank line on the screen where the H2 line should be. IE works fine, and the firefox only breaks when I remove the H2 line from the template for the “page with no sidebars”. Really strange problem, and I can’t figure out what is happening. The site is located at

https://cpanel68.gzo.com/~dainesin/?page_id=239

and the black line only appears on pages that have NO sidebar. Any ideas?
