I place several buttons in the master pages of a long document (40 something files assembled in a book) to navigate through the book to different chapters and different parts of the book (there are 5 parts).
In my firsts export (fixed-layout, of course), most buttons worked. Now after some fixng and ajusting, I re-export the whole thing, a third of the buttons just dont work anymore!!!
If I check in the document, they are still linked to the proper destination, but in the book, they are "dead"...
Also, I wonder where in the cracked file can I find the code lines to "re-connect" them if I dont have any other solutions?
