In Thunderbird when I am typing a message and hit enter it skips a line and then I can type - what I want is for the next line of typing to be right under the line of type that I just finished typing. If I want a blank line between two lines of type then I would hit enter twice. How do I get this corrected - I can not find a way to stop skipping the extra blank line in either options or account settings. Thank you in advance.
