    Have you tried destroying your controls in the OnDestroy() override, and
    leave the destructor to actual memory deallocation of items that need it? As
    I understand it, deleting the controls only sends messages asking them to
    destroy themselves, so that should be done within the MFC destruction
    process, leaving the CPP destruction process to actually release memory as
    nessisary for things that need it like memory allocated with new.
