Hi, Peter, and thanks for answering!
The text really continues without being interrupted, but we can't see it. I had the printed version in front of me for comparison, and the last word of the last visible page matched, and so the first visible word matched too, after the ending of the blank pages. I was able to stretch the text frame and the text continued reflowing, but 7 blank pages stayed. It was really as if I had put 7 white sheets over my printed book, and moved the book under them.
Is that helpfull?
We don't have the 7.5.3 patch. I don't know if this patch fits our operating system (Mac OSX 10.5.8)
