Why can't Y! find my site maps?

It's right off the home page with a text link!

I have three sites right now that have been live for several months. All of them have a text link at the bottom of the page to a site map.

Google, MSN, and others find the site map no problem. They then spider the whole site. Yahoo captures the home page and stops. Ideas?

On all of the sites, the home page does have some flash, but nothing unusual. The sites have been made by different developers and I have seen this happen several times.

Does Yahoo ignore links at the bottom of a web page?
