Saving notebook as Adobe PDF, saved PDF file contains only one page

Notebook is only about 100 pages, when saving to Adobe PDF, only one page is saved and displayed in PDF.
Help to clear this question and the steps to save all would be much appreciated.

This worked for me in 9.0 in OSX: Select the sections you want in pdf. File/Print Selection/PDF/Open PDF in Preview .
