Header broken in IE/XP

I am getting reports that my forum is broken in IE/XP. I can’t see it though. Attached is what it looks like. Any ideas why? thanks!

Do you know what version of IE that is? If it’s IE7 or earlier, I wouldn’t worry about it, TBH. I guess if it’s IE8, then it needs fixing.

I’m running XPPro and IE8. The forum looks fine to me. Nothing broken as shown in your image.
