PDF Printer stopped prompting for output filename

I use the Adobe Acrobat PDF Printer to create PDFs from a variety of applications. My version of Acrobat Pro is 10.1.6. The printer is configured to prompt me for the output filename, but never does. It used to work, but I can't figure out what has changed. I have done a repair of Acrobat, and even went so far to uninstall and reinstall.
