Actually this can cause a problem in Word 2002. In earlier versions, if you
delete header content, the header paragraph actually does disappear. In Word
2002 it not only stays but takes on the style of other header paragraphs (if
you modify the Header style). So say that, for example, you want to put a
border on your header text in one section and have no header in another (or
a different First Page Header). If you modify the Header style to include
the border, then you get a bordered empty paragraph in all sections. Worse
still, an undeletable header paragraph in Normal.dot will cause formatting
problems in labels.
