Problem editing PDF text in Acrobat 9
I am baffled about the use of the Touch Up Text Tool in Acrobat 9. My question is that sometimes when I click on it and then click on a point in the text to edit, nothing happens. In my case, I have received a book file in PDF from someone else, and am not able to edit it. He insists that the file is not locked. On the other hand, files I create in Word and save as PDF are easily edited by the touch up tool. Is there some reason a file cannot be edited if it is not locked? Is there something I'm overlooking?
Thank you for your consideration!
