Some of the chapters I have started with a portrait of the person by using the method blank diagram, save as chart etc. then insert the chart into the book. I set the page format as "chapter". If I then view the book at the page of the portrait I can see the heading with the chapter number and the title from the inserted chart. If I then page forward then page back to the portrait page the heading is still present and visible. If, however I page back then forward to the portrait page the heading is no longer visible. If I then refresh the book the heading reappears.
I have another chapter where images have been inserted using the same method but are not the first page of a chapter so have the settings format header 1. In a particular chapter I have two pages formed in this manner each showing a page of the same document. The first one of these pages exhibits the same behaviour as described above for the portrait. The second of these pages performs correctly. If I reverse the order of the pages then still the first page malfunctions.
If the saved chart page is moved to be within the chapter and not its first page there is no improvement.
I have tried reducing the size of the image on the page in case the header is somehow being hidden but that does not help.
This behaviour does not seem to affect all pages added from a saved chart. I have one such page, more portraits, which does not show the header at all even after rebuilding the book. However if I move the page on past the following page (which is part of its chapter) then the header appears but still malfunctions as above described.
Some pages added via the blank chart method perform correctly but I am at a loss to understand why some are OK and some are not. As far as I know all have been added in the same manner.
Chart and report pages all seem to work correctly.
I would be most grateful if someone is able to point out what I have done wrong or what I need to do the the book to correct this problem.
I hope that my description is not too rambling but I find it hard to describe such weird behaviour.
many thanks -- Peter
