Go buy a copy of Macafee, or Dr. Solomon Anti-Virus and make sure it comes with "Bomb Shelter", hint: Dr. Solomon seems to have free virus updates, Macafee doesn't but its the same thing!

You can install the other stuff on the disk, but it just slows your computer to a crawl.

With Bomb Shelter active you will get a little pop up whenever Netscape would have normally crashed, you press "Recover" and keep on going.

No more blue screen and I keep on working!

This is the only thing I have found that actually works. You can't fix netscape and AOL owns them and sucks even worse so don't expect anything better soon.
