FCKeditor - extra Par tags inserted

Trying to figure out why extra <p> and <p> nbsp </p> are inserted at the start and end of the text.

  1. cype ABC in the empty editor box
  2. click Submit
  3. view the source of the page and look at the FCKeditor_OnComplete function; HTMLToLoad is what you submitted: <p>ABC</p>
  4. without changing anything in the ditor box, click Submit again
  5. view the source of the page again and look at the FCKeditor_OnComplete function; HTMLToLoad now has extra opening and closing Paragrah tags: <p><p>ABC</p></p>
Under slightly different circumstances a blank line is also added at the bottom of the text, like so: <p>nbsp;</p>. This page doesn't demonstrate that because I don't want to complicate this example.

Why is that happening and how do we prevent it? I'd appreciate a response sent to sp27@cornell.edu.
