Thanks IMacQuarker for the advice. I tried each of your suggestions, but still have a bit of trouble.
In my Edit>Preferences>Preferences, I couldn't find a Direct to PDF option. Usually, I have the selection of Creative a PostScript File for Later Distilling chosen, but I fear that may not be the connected to what you advised. Making sure I had my Acrobat Reader 5.0 chosen as my distiller (It's usually set to PhotoShop 5.0), I attempted again to Export>Document as PDF, but Acrobat Reader couldn't open the file as "...it is either not a supported file type or because the file has been corrupted...". Attempting to Distill Immediately only resulted in Quark telling me "Acrobat Distiller could not be launched [-38]" even though Acrobat immediatly opened up on this command.
Additionally, I attempted to Print>Save to File, but while there is the Format option of a Acrobat PDF, this option is grayed out, and cannot be selected, leaving me only the choices of PostScript Job, EPS Mac Standard Preview, EPS Mac Enhanced Preview and EPS No Preview.
I've no doubt that there's something either missing or miss-chosen on my setting or Distillers preventing me from fixing this or keeping these setting away from me, but I'm at a bit of a loss as to what it might be. Any additional advice or ideas would be very much appreciated. Thanks again from the previous advice, as it did give me something to work on and towards.
