The Apple patch fixed my problems.
Because some people are still having problems I did an exhaustive test on Cronos Pro, the font family that I was having a problem with. I created a document in Word 2011 with one paragraph in each of the fonts in this family, there are 27 of them! I created a PDF by the simple Save As option and also by the Print to PDF > Save As Adobe PDF option since this method seems to do more work and take longer and has different dialogs so I think it uses a different conversion engine ...perhaps the job is passed off to Acrobat.
I tested all of the fonts in this family at the point size I was having problems with as well as smaller and much larger. I even specified fonts so large that they overlapped due to the vertical space setting.
In all cases the PDF looked exactly like the Word document. None of the fonts exhibited any departure from the way they displayed in the Word document except that the Light fonts when very small (12pt) tend to be a bit darker in the PDF.
I never installed the Fix others talked about on this forum, I just installed the Apple patch over the Apple 10.6.7 Leopard update.
Anyway, that is my experience for what it is worth, I rarely use the other apps mentioned on this thread as also having problems so I didn't test them.
