When I compose a new email or reply to an email, whenever I press enter to get to the next line, there is so much space. It looks like a double space. So I tend to leave it alone thinking it looks fine. Because it looks worse if I hit enter twice. When I look at the email later in Thunderbird or whatever, that is when I see that it was really a single space and looks bad.
It only happens when I am in HTML mode. Otherwise, it composes properly. Is there a reason for this? It looks horrible when composing.
