using WP 3.2.1 I went into the editor & made a change to the code which moved the thumbnail onto a line by itself under the title and centered it.
new code reads like this:
” title=”<?php the_title_attribute(); ?>”>
<p align=”center”><?php the_post_thumbnail( ‘cat_post_thumb_size’.$this->id ); ?></p>
Hope this helps.
