Quark 6 and corrupt font error message, printing to PDF

When I am printing from Quark Xpress 6, no matter what printer or ppd is used, Quark reports that "The font Helvetica may be corrupt and may be substituted with Courier [108]" . Quark Xpress 6 will also make the same warning for any other Helvetica font being used. After OK, PDF-X-Robot automation has been interrupted. Also, I can't batch process documents all night unattended like i had been because the damn message requires an operator OK.

I have had this Quark Xpress 6 font error with other fonts, they are never substituted, they will always print correctly if I just OK, and they all work without a hitch in InDesign, Quark Xpress 5. They also print fine without a font error message in Mac OS 9 and Quark 5 using same suitcase, documents and font library?? I am running PDF-X-Robot 081004, OSX 10.3.6, Mac 2Ghz dual G5. Using Quark 6.1, Suitcase X1 and InDesign CS 3.0.1. Will Quark Xpress 6.5 address this damn problem?
