Thank you for your time being invested; much appreciated. I received some
comments on the 32bit, suggesting as it was 32bit, it might not be worth
any one's extended time to sort and just move to 64bit platform asap, as
that seemed to work without issue.  I can see the point on moving from
32bit, but I don't agree entirely as there are some very useful 32bit
computers stilll out there and it would be nice to know at which point the
coding caused issues just on 32bit.

I'm afraid my learning-curve on the code base involved is steep :-)

Habs.
