I started from scratch and re-designed the theme totally. Well, in fact everything looks the same, but it is not. All has been rewritten. The only browser that thas still some difficulties with the site is IE5 for macintosh. Mot thats due to a real ugly bug in that browser, and would require extreme coding on my side to get fixed. I guess they are just unlucky in this case, the IE5 mac users. Sorry!. But if you are one of them, you can still access everything, though.
