almaink:Not to intrude as I don't use windows but who told you export was not the recommended way to make PDF's?
Unless, you have "Create postscript file for later Distilling" checked on, in the Preferences, you may be looking for trouble. If the Quark document is not graphic intensive, then you should be OK.
I belieive I read a Quark-released document, years ago, saying that with graphic intensive document, you should not use the internal capabilities of Quark (JAWS) to create PDF, it was better to use Adobe Distiller capabilities. I can't find that document anymore.
Maybe somebody can chime in.
