It does not bomb at all. But, I need to get to the bottom of this. I
have a function SetFieldText that does use FldDelete and FldInsert for
editable fields and FldSetTextPtr for non-editable fields. But, what does
FldInsert do that allows me to use these literal strings?
I guess I could take your suggestion and make the field editable then
change the text and switch it back to non-editable but I'd like to
understand what happens that makes one method work and the other not work
(even though it seems to work).
Thanks
