It is just a test program to demonstrate the problem, when clicking on one
button, the program accesses the database with IBO, with the other button,
it accesses with BDE

the program does nothing but a select to populate the dbgrid

when inserting a record (with the TDBNav object) with IBO link I just got
the error message.
I have suspected readonly flags, but, except for the dbgrid's readonly flag
which is unset by the program, all the flags are set to false
