Although the compatibility of these webpages has been checked with several browsers, including: Firefox 3, etc. Explorer 5.5, 6, 7, etc. Netscape 6, 7, 8, 9, etc. Netscape 4.5, 4.6, 4.75 (Unix) the behaviour is by no means identical across them. At present the site is targetted primarily at Firefox and later. Performance degrades progressively and most noticeably with earlier versions of Netscape. If you find incompatibilities that seriously effect the usability of the site, or encounter new problems with more recent browser versions, please let me know. If you have solutions to the problems encountered, even better!
