Ok, I'll drop this one, but can you resend the above referenced patch so
I can apply it?

I'll also update your last patch you sent as well.

Sorry for the delay in working on this, my access to a samsung laptop is
now gone, and I've been swamped with other stuff.

You seem to have a much better understanding of it in places than I do
at the moment, combined with a strong need to keep it working properly
:)
