It is a huge change and may require multiple inheritance. Any other suggestion? > If you only pass a shared_ptr out of the DLL, instead of a raw one, that shared_ptr keeps a pointer to the DLL's delete, so no matter where it ends up getting deleted the correct delete gets called. That has all sorts of other consequences, so YMMV. ~ Scott
