Hi amy:
ok.. I havent done much Quark to PDF conversion lately, so things might have changed a little. I can tell you how i used to do it running Quark 4.
It worked for us by having Adobe Acrobat installed on the computer. I would treat my Quark document as if i were printing it, then when it prompted me to select a printer to send to, I would chose "Acrobat PDF Writer". It would then ask me for a file name and a few other things, then would print to PDF for me.
Again, I cant promise it still works that way, but in theory it should. If i am wrong, I appologize. Hope that was helpful.
