Suddenly my container field won't show the content of a PDF. In some records, I see just an Acrobat icon and in other records, the entire field has a gray background, as if it's trying to display the pdf and can't.
Not sure. IE is still there, although it's not my default browser.
I had both Acrobat Reader and Acrobat DC installed. I uninstalled Reader, and Filemaker launched Acrobat DC automatically when it encountered a PDF in the record.
I uninstalled Acrobat DC, and now Filemaker is trying to launch whatever app is used to read PDFs (i.e., asking what app to use).
EDIT: I should add that this initial behavior in my OP started a couple of weeks ago.
