When typing a message after completing the first word I hit the space bar
and the word jumps down to the next line. On typing the second word, this
stays level with the first word as do subsequent words until I reach the end
of the line or I hit enter to start a new line. Every time I hit the space
bar after the first word on a new line the word drops down to the next line,
so all the lines of my messages become double spaced. Except this message
which is fine!
