ID6 crashes on exporting PDF of a book no matter what preset, get stucked in random places, in different books, but always the same place in the same doc, this happen to me with every book i've tried to export (selecting all the files in the book palette and then "exporting book to PDF")
individual files exported ok.
CS4 version of Indesign can manage the same file and exporting the whole book.
Mac Pro / 2.66 GHz Quad-Core Intel Xeon / 3GB 1066 MHz DDR3
InDesign CS6 8.0
ps: after 38 views and no clues i start to believe there is no solution
