I am using the trial version of Acrobat XI Pro In Windows 7 to compare two pdfs. These are two different versions of page proofs of a book. I need to see when text has changed, been deleted, or especially moved from page to page of the book. The compare function is flagging some cases where text has moved between pages, but is missing other large movements of text. For instance, on p. 287 a long paragraph was added (compare flagged it). Some of the text that was on p. 287 in the old version therefore moved to p. 288 in the newer version--but compare did not flag it.
If I can't fix this, the compare function will be useless for me.
Is there something I need to do differently?
Thank you so much for any help.
