When I execute a script in FileMaker 15 that has been reliably working in FileMaker 14 and earlier versions, it writes a PDF file to my desktop. If I then double-click it to open it, I get this Acrobat message.
Using Apple Preview, the result is the same.
Using the Print menu and the OS-X PDF option works fine in FileMaker 15 just like 14.
However, producing the PDF using the Save as PDF in FileMaker 15 is useless. Doesn't anybody test these things before the program ships?
