We've just recently upgraded to CS5.5 and discovered that we cannot go to the print dialog box and 'Save as PDF' from either OS listed in the subject line. The error reads: "The Save as PDF options in the Printer dialog are not supported."
We do not get this error when doing the same thing from any of the MSOffice applications or Safari - it appears to be restricted to all of the Adobe Creative Suite (Standard) applications. Is this a restriction in CS5.5 that you must either export to PDF or Save as PDF from within the application's dialog box - not using the Mac system dialog box?
Thanks for the link. It still doesn't explain why this is happening on the 10.5.8 OS. I also forgot to mention that we are using Acrobat X Pro. I was aware of the OS change with creating PDFs, but I find it odd that some applications work and the Adobe apps do not. (?)
