What Version of FileMaker and what OS?
I've never seen this before.
My bad. Accidentally opened with version 16.
Version 17 is robust. (V16 should work though.)
Problem is when editing Custom Function using FM 22.214.171.1240 / Mojave 10.14.2
Again, all is well with version 17.x
Thank you for your support.
I'm glad my question helped you figure it out!
Mojave does have a few bugs to be ironed out that's for sure
