VCurran: We just moved from Frame 2017 to 16.0.2.916 (whatever that means).
16.x is FM2020.
16.0.2 might be seen as the 2021 release.
.917 might be the latest update for it.
Anyway, useful info for the contributors here.
When opening an older version .book and/or .fm files, the newer product usually pops some notifications that the files will be updated to the current release [binary] format. It might be worth:
a. preserving copies of the FM2017 documents under other names
b. opening them in FM2020
c. saving & closing them
d. re-open, checking for any issues
We then might move to just how you are rendering to PDF, as there are 3-4 different pathways for doing that, and possible issues with JobOptions or Publish (.sts) files.
