Andrew, may I ask what you use to post on here?

You don't need to, it's in his headers: "knews 1.0c.0"

When you do post your & subsequent replies from others posts lines
do not wrap properly & I have to scroll sideways with the risk of
moving onto the next topic etc.

They display properly on this machine.

This only happens on your posts & on any subsequent replies to
your posts...

Just thought I'd ask if there was something not just right at your
end or mine?

As you seem to be using "PiaoHong.Usenet.Client.Free:1.65" I'd wager
it's your end that's getting its bits in a twist.
