For some reason, my web site was the first that I ran into which had a problem with Internet Explorer 9. Luckily, I found the problem quickly.

The navigation buttons on the right were rendering flatly. With an inspector, I had noticed that the width img tag was defined, but for some reason the height wasn’t. I have no idea how that happened.

Now, on other browsers, it just proportions the buttons and everything’s fine. Well, on IE9, it didn’t do that, and made the image flat. So, the fix was simple… I just pulled up the image and defined the height in pixels, and hit save. Presto, site operating properly.
