I am using a child theme derived from the thematic sample one with WordPress 3.2. Some of the pages have links (both external and internal) on them. Most don't work. The code seems to be the same for adjoining operational and non-operational links. I have spent hours with Google without success so far!
One problematic page is http://locus39.net/ddogs/?page_id=2 - the first two links do not work but the rest do.
Here is an example from that page using 'view page source'. The first link does not work, the next one does:
