When replying or composing a mail, pressing Enter always adds an extra blank line. How can I stop this?

I type enter and there is an extra blank line Like this I can't seem to find a way to stop it. It doesn't affect bullet lists: * Bulleted list item * Bulleted list item But I can't provide a tidy chunk of information, e.g. when providing my Address to someone (where bulleting doesn't make sense) Probably something obvious - I tried from 'Format' menu changing from 'Paragraph' to 'Body Text' but it doesn't seem to stick. FOUND IT: From MAIN APPLICATION window Menu...Edit...Settings...UNCHECK 'Use Paragraph format instead of Body Text by default' I must have checked it at some stage (or maybe it's the default) Sometimes I enjoy a conversation with myself...but in any case maybe someone else could find this useful.
