Well, the technical issues are well understood, but it came down to coding 
style and approach, rather like Constable and Monet working together on a 
picture, with Picasso contributing when he has a weekend off!

If you go to the original Columbia archive at 


you can get the version 3 patch (although for me it came as a '.bin' file and 
had to be renamed '.diff') and that should be fully effective, although 
without any 'extra log warnings' that Ross had mentioned.

Hope this helps,
