Hi Alan!
It is probably related to it:

DoMacroSubstitute syntax was changed since IBO4.6A.

// IBO4.5B and older
procedure TIB_Dataset.DoMacroSubstitute;

// IBO4.5A and newer
function TIB_Dataset.DoMacroSubstitute( const ASQL: string ): string;


Probably somewhere there was an old bpl-file.
Try carefully deinstall IBObjects
(remove all IBO[your Delphi version]*.bpl including:
Documents and Settings\...\My Documents\Borland Studio Projects\Bpl\
Program Files\Borland\Delphi(your version)\Projects\Bpl\
WINDOWS\system32\
)
and install IBObjects again.

I shall be grateful, if you will inform about result.

Best regards,
Ramil
