Colleagues, I have been asked to comment on proposed software upgrades, one of which is Netscape Navigator 4.x. I understand from various sources, not least this list, that there are compatibility problems between earlier versions of Netscape and version 4.x. Specifically I am interested in chemically orientated helpers and plug-ins and I would like to know if there is any information available concerning the current state of play of, for example, products like Chime, NPJCAMP etc. Comments on Java and JavaScript compatibility between 3.x and 4.x would also be of use. Pointers to Web pages would be fine. Many thanks for your help. C. Anthony Lewis C.
