Answers inline below:
**have you tried playing with your system settings to see if it could involve the decimal characters used (. vs ,)?**
Seems to make no difference.
**have you tried if you can switch using system formats to file formats or vice-versa?**
I tried "general", but I don't know what you mean about "file formats"
**does the calc has global storage?**
No, it's per record.
**is the calc stored or unstored?**
It's unstored, but the data for the example shown was already written to the table.
**is the field belonging to the same TO as the layout or a distant one?**
Same one.
**what happens if you just do a refresh window?**
Nothing.
**What version of FM? Can you try different versions?**
16, Don't have any other version.
**Screen capture is a mac. Would it be easy to validate if the behavior is the same on a PC?**
No idea.
**If you replicate the basic components in a sample file, do you see the same behavior?**
It works as expected in separate file.
The layout in question has tons of calculations, graphics, and other features, but the calculation is happening the exact same way as in the sample file.
Not sure what to conclude there.
Since the data are already in the fields, but the layout simply won't display them until I click in and out of the field, how do you debug that?
Good questions, thanks!
