Thank you all for your helpful comments and suggestions. I had, in fact, tried most of these, sadly without success as yet.The piece on which I am working is for SATB choir with piano accompaniment, being written in long score as it is polyphonic in nature. What is happening is that the lyrics are appearing in page view at unacceptable places, such as within the piano part or way above the stave. When I correct these faults on page view, it is then right for the page upon which I am working; however, upon moving to the next page and working on that, i find that the part I had just corrected reverts to how it looked before. Will I have to print one page at a time, then move on? That will be very laborious in a piece with up to twenty pages.
Further ideas from experts in this field would be very welcome
