I have now resolved the problem - this is an undocumented Microsoft
"feature" which occurs because (as the help facility will tell you) you
can only use one signature in an email. It generally happens if you have
default signatures set up. If you create a new email or reply to an
email, your default or response signature is inserted automatically. If
you then delete that, type in some text and insert a different
signature, Outlook has not registered that you have deleted a signature,
so it takes your text as being a signature - and replaces it with the
new one! Clever, eh?
