I've just had a look at your profile in Internet Explorer, Firefox and Chrome. It displays fine in IE and FF but the issue you described is present in Chrome. Is that what you're running?
There might be some compatability issue with Chrome but I'm afraid I wouldn't know where to start figuring that out. I would suggest contacting the person who provided the code for the content holder you're using. They might be able to explain what's wrong.
Sorry I can't be more help.
