ah, I found what the locking bug was.  It is only when using WYSIWYG.  If I use normal wiki editing, it works fine.  If I use WYSIWYG, it does no locking and two people can edit the document.  guess I really do have to wait for the new WYSIWYG release :(.  I was hoping not to slow adoption as people here find that difficult(dealing with business types).

thanks,
