I fixed a problem with my blog that appeared only in Internet Explorer 6. Some people are forced to use this browser in libraries or at work. If you are not being forced to use Internet Explorer 6 at least upgrade to IE 7, better yet to Firefox.
Luckily I was able to use VMWare Fusion on my Mac and load a fresh copy of Windows XP that had Internet Explorer 6 in it to track down the problem. It turned out that some images in the sidebar were a couple pixels larger than the width of the sidebar causing Internet Explorer 6’s rendering engine to misplace the second column.
