This is not quite a correct interpretation. After committing the
change, the Invalidate... methods set a flag so that, *next time*
that record is accessed, IBO will know that it must re-fetch that
record from the database into the buffer (or, in the case of an
Insert, it must fetch the new record and add it to the buffer).

Not that I recall -- although it is a VERY long time since I looked
at IBO 3.6, to know what might have changed. You may read the
release notes that were distributed with 4.5Ai, to check up for
yourself whether there is something introduced in IBO 4 that might
impact on the behaviour of your old code.

You probably need to look at the CommitAction setting of your
dataset. As an experiment, you could drop a TIB_Query into your form
and inspect the default setting of CommitAction; and then compare it
with the setting that was imported by IBO4 into your old project's datasets.

What version and edition of Delphi are you using?
