I remember in word for windows (Either 2 or 6, not sure) on my 40MHz 386, you could watch it reflowing text if you edited a paragraph near the beginning of a multi-page document. It would correct for widows and orphans, which would cause surrounding pages to potentially do the same. It could take a non-trivial amount of time to stabilize, and if you printed a document before it did, you could end up with duplicated or missing lines at page breaks.
