I wonder if anyone knows why the layout of a kindle book changes even if you don't change the font size. For instance if I am reading a book and I do a search within the book sometimes the words are on a different "page" than when I originally read them. For instance, somtimes a chapter ends and there is almost a full screen of blank and I hit next page for the new chapter to begin, but later on if I look at the end of that chapter again it is at the end of a screen. another example is the last sentence on a screen might be the first sentence on a screen as I am using the prev page and next page buttons, but I haven't changed the font size so I don't see what the display would change. Am I making sense?
