Unfortunately, different browsers display the same information sometimes in a slightly different way, although so-called "standards" exist. We have tried to optimize our Web site so that the visual appearance is comparable in at least the commonly used browsers. Extensive tests have been performed with Microsoft Internet Explorer (versions 5.0x, 5.5x and 6.0x), Netscape Navigator (versions 4.6, 4.7 and 6.2), and Opera (versions 5.x and 6.0x), all on a Windows platform. Best results have been obtained with all tested versions of the Microsoft Internet Explorer.
