In reply to these two last suggestions, no, there were no blank spaces in the Word document, and not all the cursor will in the world will make those blank spaces disappear. However, we have just come across an earlier discussion thread which we now realize is our problem too, a Bug which makes Pages useless for much academic writing. Here is a comment posted as part of that January 06 discussion: "Pages 2 makes no provision for breaking footnotes across page boundaries. The result is strange and amateurish-looking pages, filled with puzzling gaps and white spaces, in any academic paper that has discursive (long) footnotes.
Almost all academic papers, at least in my discipline of history, have discursive footnotes. Mine are no exception, and all of the book chapters and articles I write in Pages accordingly look as if they were composited by a blind man when I print them out.
The effects of this problem are clear on pretty nearly every page that a historian (or other academic or advanced student in the humanities) writes. To make the notes look normal enough to pass on to a colleague without embarrassment, I will have to save my documents into Word and re-open and tinker with them there.
This problem seems to me to be a bug, not a missing feature--acutely so, in a program whose raison d'être is the production of attractive-looking text documents--because I don't know of any other commercially-available word processor that has this problem: not Word, of course, not Nisus, not Mariner Write, not Mellel, not AppleWorks. (Indeed, not even WriteNow, a program last updated in 1994.)"
We have just emailed our own complaint to Mac feedback, too. Christine and Martin
