To create the pages with names and links, extensive use was made of layers; layers do not render well in some browsers and with some operating systems.
You should not encounter difficulties in the following cases :
Mac OS9 : MicroSoft Internet Explorer (MSIE),
Mac OSX : MSIE, Netscape and Safari,
PC Windows 98 : MSIE

Be aware that on opening the page, you will be loading 450Ko of images; thus using modem/ordinary telephone connection, this will take some time; ADSL/cable connection : no problem
