I have a the following document which uses the book class. For some reason, the page number is, on the first page, at the bottom of the page and centered (article like footer). The next page has the number up and on the left (with the chapter title on the right): book like heading.
Why do I have two different ways to show the page number? I would like to have the normal book class heading (i.e. the page 2 heading) for the whole document.
