Inserts empy paragraph at beginning of node

If find that when saving a new node, ckeditor inserts

at the beginning of the copy. I need then to edit the node to remove this. Once edited, the paragraph does not return.

This is quite annoying and I wonder what is causing this. Moreoever, I want it to stop, right now!

Does anybody else have experience of this or better still, know of a cure.

BTW, I'm using the wysiwyg module but think this problem originates from the ckeditor library.
