The /index.html page (home) and a test page I have created /test-page, have a white line that appears at the bottom of the header graphic. This line only appears on pages where the graphics that use the regions below the header (1, 2 and 3) are utilized as link. You can see all the "regular pages" on http://www.idomagic.com work fine.
I have dug as deep as I can and am at wits end. Honestly, I am not a theme ninja, so I bet it's something simple and obvious. I have turned off Optimize CSS files and all caching so anyone wanting to take a look with Firebug will see anything. I also have Drupal for Firebug installed, but I have not figured out how to use it.
I know this is really specific question.

You will find that those elements are in a table and the table body (tbody tag) has a white line (border).
...
tbody {
border-top:1px solid #CCCCCC;
}
This is Drupal bitch slap for anyone using tables for layout, shocking.
