The site also relies on a frames layout where several web pages are combined into the one you see in your browser [or not in your case] and, once again, many browsers stumble over correct interpretation of frames.
In fact, a quick check of the site shows some very serious potential problems.
Relying on pop-up windows as a fundamental part of the site navigation is always a mistake. These days more and more people either use pop-up blockers or use browser software with such features built in, so the site, to be viewed properly, requires the security conscious to either re-set their security measures or use alternative browser software.
The link to "Tok's News Letter" leads to a PDF file and there is no warning that clicking on it will initiate Adobe Acrobat Reader in the browser or prompt the site visitor to download said file. In fact, although it should do one or the other it actually does neither since the link is dead and leads to an error page.
Sorry, but I seem to have gone into a site evaluation here and have left the topic to hand.
