The problem is caused by the sitename & sitedesc headers in the top left corner of the theme. These occupy the full width of the theme, so the top-right description div is actually underneath these headers. When you try to click the link, you are actually just clicking on the site title.
The problem can be solved by setting the width of the left headers to 500 px or thereabouts.
1. Go to the theme editor.
2. open the stylesheet
3. find the “#header h1.sitename” and “#header h2.sitedesc” entries
4. Add “width: 500px;” to both these entries
