Thanks...saw it after I'd already posted my comment.
copying and pasting from grok responses loses the paragraph divisions that grok shows and adding empty lines using the ENTER button in the FR text box after pasting and even in other text editors DISPLAYS the extra white space until one hits PREVIEW, and presto, all the white space lines disappear ...
there must be some kind of embedded invisible formatting in the grok text, and the only way i found to fix the paragraphs in FR after pasting is to add HTML “P” tags where one wants a paragraph break ...
