Comment, thanks - Sorry I've been distracted from all this helpful support here and have taken way too long to respond.
"same problem with a Brand new file created from scratch?"
Looks like the problem is solved!
I exported a bunch of the records into a new Filemaker file and printed out a list from Table view that successfully included all of the records.
The original file continues to refuse to do that, printing only one record. I even made a copy of the original file again and that, too, only prints one record at a time from list view when instructed to print all records being browsed.
But the new Filemaker file I exported to, got all of the fields from the old file as instructed, but none of the layouts, scripts, saved finds, etc. So it's really not a practical (read: easy) solution if I have to really rebuild all of the 94 layouts in this file, as well as the scripts and saved finds.
So if creating a copy of the original file brings with it the printing issue, and exporting the records into a new file brings the data over, but none of the layout formatting, scripts, saved finds, etc. do I have any other options?
All this was done in Filemaker 16 on my 2022 M1 MacBook Pro using the latest version of the MacOS Ventura 13.1
BTW - I just noticed that the theme of the single layout of the newly crated File that succeeded in printing out all of its records in list view was not Classic. It was Enlightened.
I see that "Classic" is not one of the available themes, but it does offer the option of importing themes. Am I courting disaster by importing the Classic theme from the source file that is the source of my problem?
