This site uses DasBlog as it's blogging engine. One of the themes that comes with DasBlog, Project84, has a rendering problem in IE7 that causes the footer to bleed into the main page somewhere a few inches from the top, when it should, of course, display at the bottom of the page.
The problem turns out to be only one line in the style.css file:
html, body{height:100%;}
Comment this out and the page should render correctly. This also affects the Project84Green theme.
I viewed the corrected style in Firefox 1.5, IE6 and IE7 and did not note any issues.
