The TYPE TEXT tool in the 'fill in forms' menu does not always format well when pasting text in. The text box exceeds the page size, text does not wrap, box is not editable, as far as I can tell. It might be the difference of copying from email vs. Word, which seems to work fine. In the old Acrobat I used this tool extensively rather than a comment box which is not always appropriate. I think it was just called a text box in the old version.
