[NTG-context] printing problem (defined)

I apologize if this amounts to hijacking a thread. The problem Using TeXShop (latest) I can produce but not print a PDF file that has both the TeX Gyre Bonum from GUST and the GreekKerkis font from Thomas Schmitz' ancient Greek module. This file will, however, print with Acrobat Pro 7 and 8. The problem is not with the fonts themselves—test documents with only Bonum or GreekKerkis behave as they should. The practical solutions are obvious. But if there is something I can do to facilitate a fix for this, please let me know. Alan PS I will be away from my setup for a week starting in about 5 hours. A.
