Thanks for coming back to me.

First of all, I was wrong; I thought I had copied your settings exactly but now note that you have "show paste options button when content is pasted" checked. On mine it was not and, when I check it, find I can copy from the web or other documents and the formatting rules stipulated will be obeyed.

Not sure why this is - so much of Word is a mystery to me, but I am now out of the hole, and very grateful for your help.

(Still maintain that Ctrl-Shift V works well and am surprised that Microsoft do not use it.)
