I have narrowed it down to the slide rules for sure.
I deleted all the containers and re created them. If I assign slide rules to the containers they periodically show up when printing. If I turn the slide rules off they print! Unfortunately I need the slide rules for printing... Does anyone have experience with interactive container fields and slide rules?
This sounds more like a bug than anything else. Sliding should be the same on Mac and Windows systems.
I recommend going to Report an Issue in this forum and reporting this to see what the FileMaker Techs have to say about it.
I posted the issue there. Thanks for the direction.
