I am sure that you mean Internet Explorer 5.1.7. Netscape went from Netscape 4.8 to Mozilla-based Netscape 6.0, which was tré-crappy. The 5.x version of Netscape was not released to the general public. Perhaps, you should try to access this site with a different browser. Netscape 7.02 will work with MacOS 9.1. So too will Mozilla 1.2.1. iCab and Opera are also available for MacOS 9.1.nikaeda said:I have an IMac 350MHz/128mb6GB OS9.1. I'm using Netscape 5.1.7. For some reason certain websites refuse to load up properly. They used to work fine. I know the browser has 128bit encryption, so I'm stumped. Any ideas?
