Page Text Chopped Below Header

[RichUE]

I have a document where the first line of the page is chopped off. The risers
on all the characters on that line have disappeared! I can add an extra
paragraph break to hide the effect, but what is causing it? The paragraph
format looks okay. I have tried changing the header height by dragging the
header boundary using the transition mark in the vertical ruler.

What can you suggest?

Hi Cindy
Taking your suggestions in turn:
I can't see a graphic in the header. I tried turning on Picture Placeholders
and there was no difference, so I turned them off.
The document looks the same in Print Preview, but I was really surprised
when I printed a sample page - there's no problem with the print.
The on-screen appearance was fixed when I copied the entire contents into a
blank document.

So is this a feature without an apparent cause?

Thanks for your help.
