Updated to FM Pro Advanced 13.0.4 and FMS 126.96.36.1990 and went to open an existing, perfectly working, database with several PDFs in container fields on my desktop.
Now, all container fields don't show any content. I know the data still exists in the containers as when I try CNTL-Click the "reload" message appears, and I can export the continer contents to an email or file. All the container fields are set as Interactive with the "start playback automatically" box checked. The format is set as: "reduce or enlarge image to fit".
When I log into the same database with File Maker Go, the contents of the containers appear as normal.
The content just stopped showing up on my desktop.
