This is a nuisance that I've been meaning to report:
In FMPA 14 on a mac, when editing a calculation e.g. in the Script Workspace.
Enter a calculation area (such as the value calculation of a variable), and type "Fieldname ≠ Fie" (where "Fie" is the beginning of a valid fieldname or expression in the database).
Expected behaviour: Autocomplete suggests "Fieldname"
Actual behaviour: No suggestion
Workaround: Backspace to the ≠ sign and type the space again.
I can't reproduce this on FMPA Windows 14.0.4, but I'm not sure how to get the ≠ sign; I'm pasting it.
