Topic awaiting preservation: Netscape && RegExp

Have others out there come across some glaring bugs in Netscape 4's regex parser? I have been "fixing" many bytes of my own script to cope with the inadequacies of NN4.

Is there a single source detailing all the bugs?

Hmm... i vaguely remember something about NN doing regexp's differently if you say <script language="javascript1.2"> instead of just <script language="javascript">... are you doing that?

Yup. Just checked to make sure.

I can't seem to convince the bosses that supporting NN4 adds significant costs due to bugs.
