I was sorry to hear of the difficulties some of you were having accessing our website. I must confess these technical issues are not my strong point but I emailed the website developers and have heard back from two of their staff as follows:
"I have tried accessing the site with the latest version of Firefox (2.0.0.4) and all works fine. We do not have Vista and Firefox installed on any of our hardware however the latest release of Firefox does apparently fix some issues with Vista. The application was designed to support both IE and Firefox."
"I have Vista and Firefox (although I have the latest version 2.0.0.4) I have just tried the site and all works fine."

If any of you are having continuing difficulties and wouldn't mind taking a few moments to let me have some detail, I'd be really grateful.

Thanks for your time.
