This is a weird problem ... or maybe actually something really simple that I just can't seem to figure out, but I have the permalink coming in as a heading and then as a "Read more" link below the body ... anyway, the top one is in an <h2> tag and the Read more link is in a <p>. When you attempt to click on them, they respond as if CSS is causing them to shrink on the a:visited or something. I don't have anything like that in the CSS.
The three links can be seen at the bottom of this page where it says "Ask The Doctor Blog". Try to click them. Am I going looney?
