it sounds like you cahnged the view. The Normal Layout doesn't show headers and footers. To get it back, Go to View>Print Layout.
I accidentally hit some random key combination and now for some reason in Print Layout view, the top margin doesn't display, and the cursor seems to be right at the visible top of the page. Everything looks fine in Print Preview mode, and prints correctly, but the view just isn't accurate. It's something I've done to the template, because this is true for all new Word docs I create.
Anyone know what I might have done, and how to change it back?
