Brain pain.

Hi everyone. I am hoping someone can help me with this.

Here is the site:
http://steve.jbx.com/vipservices/index.php

select electrical contractors and zip code 36066

The problem concerns the top and bottom left corners of the result and form tables. Each one has a corner image to round off the the corner

In Firefox the tables look correct. However in IE there is a space, or the image is inset somehow. I am competely stumped.

Any help or suggestions would be appreciated.

Thanks.
