I've based a friend's site on the Tanzaku theme. The site looks the way we want it to except for that the image thumbnails on the main page overlap each other randomly each time the page loads. Resizing the browser correctly realigns the images but this obviously isn't a solution. It seems to load correctly in Internet Explorer. Any ideas?
