Hello Cee,
Please, for the sake of completeness, go to the other thread and explain what was done to correct your password problem.
As for the Acrobat Question....
Acrobat costs anywhere from $150 - $300 per license depending on what you needs are. Distiller is part of Acrobat Professional.
You may notice that OS X offers you, inside of the print dialogue box, the option of saving to a file as .pdf (almost all OS X programs offers this. While I have not seen Quark for OS X in my personal possession, I have to assume it is there). This method of creating a .pdf file is not the same as using Acrobat.
Distiller
Distiller is a program that comes along with Acrobat that converts postscript files to .pdf files. You create those postscript files by saving them with the printer driver, and then running Distiller as a separate process. For a Quark documents that I did in the past under OS 8 and 9, I would run distiller and get really nice smooth and efficient Acrobat files.
So, to answer your question, for quality control purposes, I would track down Distiller, and fine-tune the halftoning and other options to make crisp and clean output documents.
For those of you reading along, I think there is some better Desktop Publishing software (DTP) out there called Ragtime. Go look it up on the internet... and it is free for personal use, and it is a lot more stable. The quark support forums are ON FIRE with complaints of instability and quirkyness.
