[SOLVED] Thumbnails with excerpts - not resizing or floating

I've spent several hours trying to get the "Post Thumbnails" with excerpts function to work. For the most part I have it, however the thumbnail height and width are being ignored. The full size image is showing and the text is not floating around it.

Here is a link to a category page: http://discontinuedkohler.com/category/faucets/cirrus/

Using WP version: 2.9.2
Using ATA version: 3.4.6

Thanks in advance for any suggestions.
