Oops! I was using 3.0 for development. My IIIx actually used 3.1

I thought that insertion point position was a number between the
beginning of the field to the end of the field. How does that relate
to rows? Anyway, yes, the field was a little too small in height.

This one is odd. I set the field text with SetFieldText below and if
I comment out the FldSetSelection() (don't think this is needed
because there is nothing to select, since the field is not editable),
the problem completely goes away. But I am curious.
Does StrLen(fld->text) have to = fld->textLen or be less than. It
seems like fields are changed often. Does this mean that I have to
change the field attributes (textLen) each time I change a field.
I typically use the function below to change the text in a field:
void SetFieldText(Word id, char *s) {
FormPtr frmp;
FieldPtr fldp;
FieldAttrType fa;
frmp=FrmGetActiveForm();
fldp=FrmGetObjectPtr(frmp, FrmGetObjectIndex(frmp, id));
FldGetAttributes(fldp, &fa);
/* if editable, do insert, if not, set poiner */
if (fa.editable == TRUE){
FldDelete(fldp, 0, FldGetTextLength(fldp));
FldInsert(fldp, s, StrLen(s));
}
else{
//FldSetSelection(fldp, 0,0); // no field length error if I
comment this out
FldSetTextPtr(fldp, s);
}
FldDrawField(fldp);
}
