After comverting my Word document to a PDF, some of the bookmark titles now have "5T" or "6T" added to random places. Here's a screen shot. See the entry "capitolo" there is a "5T" added before, which isn't present in my word file. I'm running Windows 7, Acrobat 9 Pro, and Word 2007. T h a n k y o u s o s u c h !
