Error "invalid short file name" when try to save as .docx in Office 2007 Word

I'm using a Dell E6400 with Windows XP Professional and Office 2007.  Whenever I try to save a document as a .docx file, I get an error message "invalid short file name" and it asks for a 8+3 format.  When I try the 8+3 format, I get the same error.  This doesn't happen for all documents, just occasionally.  If I copy and paste the entire document into a new file, I can save as normal
