About what?
Laying heavy paving slabs. I suspect your newsreader isn't displaying
threads right...

Aha! I was displaying them in time order, my usual display mode - sorted
by threads, I can see "Thanks" in context. I'm using "Thunderbird",
which seems generally OK except that sometines if I click a title with
the mouse moving slightly the whole list scrolls to the top or bottom!
