I have created an e-mail signature using a table to control the layout and
formatting. This is fine until I reply or forward a message, as the signature
then joins to the message I am trying to forward/reply to.

I have gone into Advanced Edit Table Table Properties and set the text
wrapping to 'None', which seems to work. However, when I make any edits to
the signature it resets the table wrapping back to 'around', so that I get
the problem repeated.

Any ideas?
