Helen,
nope ... it "Record is not inserted" message is showing up. Either within the
IDE or as stand alone application. The Exception is only showing up inside
the IDE.
I create a small sample project to verify the behavior. The "record was not
inserted" message is coming from within IBO.
I've traced it down to the ib_constant "E_Record_Not_Inserted" and that is
used within IBODataset.pas, TIBOUpdateSQL.ExecSQL

But how can I disable that message box/database error exception?

Regards
Gunther
