I hope I can explain this so that I can get some much needed help. I am validating a book in Kurzweil; it has an RTF extension and I have not changed it. When Kurzweil states a number change, I see this on the screen. When a book page number occurs there is no screen movement and these two functions are in no way occurring at the same time. Kurzweil says there are 544 pages in the book; the last actual print page number is 310 and this was verified with the submitter. Can someone tell me what the problem is here and do I need to be concerned about it? It is an excellent scan and I surely don't want to reject the book. I have not tried to change the extension to KES but should I do so? TIA. Jill
