Hi,
The reason for that might be the old browser and ancient OS combination. I’ve checked your site for errors and everything is in order, so this is not something related to the theme itself. It could be some IE settings (like maybe being used in compatibility mode), or just the fact that IE8 was actually the initial browser for Win7 (it was ported to XP just so that XP users get a slight upgrade).
Not much we can do in this case – it works fine in Win7 with IE8 for example, so my guess is that’s it’s either in compatibility mode or there’s some bad settings in IE8 in your case.
Regards,
