I am saying those people type the description in the box provided do not experience the problem. The issue as I am following here is coming from transferring from the word processor the editor. Remember I did my own testing copying pasting your very reviews in the review editor it worked fine.
The only difference here is obviously I did not type up a formatted reply in a word processor.
All I have said all along is that is where the returns are being done.
Your fix for you would actually cause a bug for everyone else because we want a line return to be converted to a break in descriptions comments otherwise you would not have any formatting.
My fix is a fix for you because how ever your doing things is causing you DOUBLE RETURNS which results in double spaces.
