AC97 didn't use trust center, it used MDAC, which is a totally deprecated module. That allowed it to do internal object ownership and permissions. Since maybe AC2003 that has been a declining feature. Now, 19 years after that version of Access, it is not only possible that Microsoft didn't consider the effect of a security change, but probably doesn't have that many people left who REMEMBER the care and feeding of MDAC.
What version of Windows are you running?
