It's very far from correct! The search engine works with Netscape 6.2 on
Linux (and Windows), and with Internet Explorer and Opera 5 on Windows.
(We were told it works with Internet Explorer on Linux too.) Opera uses
Sun's 1.3.1, as I recall, so I don't think this is a Java-1.1 vs 1.3
issue. (I've just checked: Netscape 6.2 uses JRE 1.3.1.)
What BTW is `Mozilla 6'? The current Mozilla is 0.9.6, so `6' seems a
decade or so away.
Which documentation do you suggest is altered and how? Given that the
Mozilla-0.9.4-based Netscape 6.2 with JRE 1.3.1 works, the finger is
pointing pretty insistently at a problem in the installation of `Mozilla
6', whatever that is, and/or its JRE.
