Thanks a lot guys for taking the time to reply...what the hell could be happening if Safari, Firefox and Chrome are all fine (I guess they are all built on the same Webkit (corrected). What would IE be doing differently? It seemed fine in an earlier version of Interspire but I don't want to go back to that as it doesnt have feedback forms!
I've cleared the cache within Interspire (the CMS system I am using) and in Internet Explorer but still no joy. I've even setup a new install here: http://www.artandepilepsy.com/version2/ (ignore the big heading text) but I get the same problem.
Here is my .htaccess file:
