This hasn't got anything to do with which JavaVM you have installed. You say your
problem's related to java script. Now that you know that, there's no need to start
using IE. IE has way too many security issues and is very vulnerable to malware infections
and hijacking problems.
Considering your problem is on Google for one, I know there aren't malicious scripts
running on the site. It must be the way Netscape handles scripts. I suggest posting
on the Netscape forum or trying Firefox. Most of us aren't familiar with Netscape
specific issues. They do have a forum.
