A few (?) weeks ago the format in which a message appeared as I type it (eg now) changed and instead of words appearing complete, a word might be broken over the end of a line. In fact, it's happened now because the 'because' appears as 'beca' on the end of line 2 and line 3 begins with 'use'.
It only happens in the box in which I type; when I post, it reverts to normal.
Is there a setting I should change?
It shouldn't happen to a pedant like me.
