I presume you mean me :) I had a hunt through the many mails you sent on

first time round. Sorry about that. Not unwilling, just unaware.

I've attached the output to a reply in the other thread.

Interesting. I wonder if this ties in time wise of when I noticed this
working..... If I find time to play, I'll maybe try reverting this to
see if it helps.
