Thanks so much!  The BodyFormat property did the trick.  I didn't need to use
the line break.  But for future information, where in the code would I add
vbCRLF, and would the line break be at the beginning of the body text or
after the attachment icon (if the message still was in Rich Text format)?

Since my original post, another issue has come up. The owner of the form
added a hyperlink to it (where it resides on a network server location) on an
intranet web page.  He made the document read-only.  By doing so, when a
person completed the form and clicked the Send Form command button, a Save As
dialog box displayed (because the code originally included the line
ActiveDocument.Save before the With EmailItem line).  We removed this
ActiveDocument.Save from the code so that the macro would run and immediately
open an Outlook new message.  Now, however, the attached document reverts to
being blank and does not contain the user's form field entries.  If we leave
the ActiveDocument.Save line in the code, a SaveAs dialog box displays as
soon as the Send Form command button is clicked, confusing the form user.  If
the document is not made read-only, and the ActiveDocument.Save line remains
in the code, the Send Form button works as it is supposed to, the Outlook
message displays in order to insert additional comments before sending, and
the message sends normally, and the attached document includes the filled out
form fields.  The Word document remains displayed on the screen, however.  
When closed, there is no Save reminder message box, and the user's form field
entries are saved back to the server location document.  When the next user
activates the web page's hyperlink to it, the document does not open "clean"
but displays the previous user's entries.

As you can see, I now appear to be way out of my element.  Thanking you in
advance for any help.
