Can someone tell me (staff) what to change in the post_parser.php file? I currently have some important modifications in this file for custom bbcodes, and I need to patch this particular file manually.

Thanks!

I would also like this too as it seams to have disabled the java popup for my spell checker on the post screen. (Yet it works fine on edit and fast reply :S)

Why not use a file comparison tool?

I wrote manual upgrade instructions for IPB in the past & used a file comparison tool which highlighted the differences between 2 specified files so I could see exactly which lines were modified.

I can't remember the name of the application that I used, but here is a Google search (for freeware apps) that may help you get started.

A good diff tool for windows is KDiff
