Hi,
As Kestrell and others have pointed out, you can run into various problems with PDF's. For best results generally, use Adobe Acrobat Reader rather than one of the browser PDF readers. And you can read about the vvarious issues encountered and how to deal with them in Chapter 10 of my book.
Regards,
David
