Sentence and paragraph separation problems

After clicking on the "REPLY TO" button and typing out my reply, my sentences and paragraphs are all ran together into one paragraph when I click the preview post and Post reply buttons... why?

This problem started after copying and pasting from a PDF document.

Strange, it's not doing it in this new thread post.

I have had the same problem copying and pasting from an MS Word document.

It appears that the format is not recognized by the web page and it just sees one block of text.

I'm not sure if much can be done about it unless you copy and paste a paragraph at a time.

There may actually be a more technical answer to this and hopefuly, someone with more of an idea on the design of ATS's html coding will let us know.
