dougalder essentially solved my problem in another post by posting this simple script to export the pdf. This way I can simply view the PDF in my default PDF reader, which will run faster than Filemaker has, at least on my machine. His post is as follows:
Another workaround for PDFs that won't display properly within FileMaker is to write a script that exports the file to FileMaker's Temp Directory and auto-opens the file in the default PDF viewer (Acrobat, Preview, etc). Something like this:
Set Variable [$Path; Value:Get(TemporaryPath)]
Set Variable [$FileName; Value:Data_Table:PDF_Container_Field]
Export Field Contents [Data_Table:PDF_Container_Field; "$Path/$FileName"; Automatically open]
Exporting the PDF should not leave the field blank as it is merely exporting a COPY of the PDF. The original will still be in the field.
Create a button and link it to the script. Put a PDF icon on it and a tooltip "View in PDF Reader" to help users understand what is going on.
