Gaoming,
We ran into this too. As Sun says: "it's a bug in Netscape" (and
apparently the only plan to fix it is to wait for some future version of
Netscape 6). Basically Netscape is incompatible with HTML pages
converted with the HTMLConverter (ie Netscape doesn't work properly with
Java 1.2.x or Java 1.3.x).
I don't have the bug ID handy but Sun has a few bug reports about this
in the bug database. Unfortunately Sun isn't going to do anything about
it (honestly it is a Netscape problem but I don't think we can look for
much help from Netscape - I don't even know how to contact Netscape...
I've tried... seems to go into a black hole).
