Thunderbird 31.6.0 sometimes fails to word wrap properly

Text lines sometimes fail to word wrap properly. Example: a sentence that contains the words "foggy bottom" , where the "foggy" is at the end of one line (when composing) and the word "bottom" is wrapped to the beginning of the next line appears like this: "foggybottom" when it appears in the "sent" folder. The two words were separated by a single space when composing. Does not happen all the time, only occasionally. I cannot reproduce this problem on demand - it only happens at random.

More on the word-wrap problem. I have confirmed that the "word wrap problem" (for lack of anything better to call it) does in fact exist. I have not been able to tie it to any plugins or other software issues other than the change to version 31.6.0. I am wondering if anyone else is seeing this issue? OS is Windows 7 professional, 32 bit. I suppose I could regress to the previous version of Thunderbird, but that would not be my first choice.

Can you confirm that you are using Plain Text, not HTML? do you use Plain Text all the time?

Can you check the following and say what you have as settings:

Tools > Options > Advanced > General tab or Menu icon > Options > Options > Advanced > General tab

click on 'Config Editor' button it will tell you to be careful :)

In the Saved Draft or Sent folder. select the email so you can read contents in message pane click on 'Other Actions' and then 'View source'

where it says 'content type does it also say 'format-flowed' eg: Content-Type: text/plain; charset=windows-1252; format=flowed Content-Transfer-Encoding: 7bit
