First of all, thanks for your assistance.

We've assigned an explicit ib_transaction as the DefaultTransaction.
But that's only there to detect if a programmer uses the connection
without a separate explicit transaction. There's a BeforeStart event
that throws an exception. But again, this transaction never gets used
because the code path is never executed to produce this problem.

Ignorance :-) I didn't know that doing that would block the OAT.

I disagree :-) Someone might want to set OldParameterOrdering=1 on
the FB server so that it can work properly with old software that uses
IBO versions older than 4.3Aa. Then for any new software, using IBO
versions 4.3Aa and greater, leave the default setting to poAuto so
that the new software can detect whatever parameter ordering the
server is using. This seems to me to provide the most flexibility.

Yes, but I believe the problems is not in FB. I believe the problem
is the IBO Ordering detection logic so it doesn't matter what version
of FB is used.

I not mixing components of FB versions. I have a clean XP image that
I copy over and then do a clean install of whatever FB version I am
