It displays well in IE but, at least on my machine, in Netscape or Firefox the background colour is missing (something to do with stylesheets I guess since there is no obvious .jpg file in the page source) so there is white text on a white background!

I worked out that that there should be text there and was able to read it by highlighting it before checking on IE. I don't know if you built the site using MS software which may explain why other browsers don't seem to be fully compatible.

Worth checking on other machines and browsers in case it's just a quirk of mine.
