U must make sure u destroy ur control correctly

1) check/debug your main ATL class destructor.
u may be doing something wrong there.

2) if u have threads running, make sure to stop them.

3) unload loaded DLLs

4) do u implement InPlaceActivate & InPlaceDeactivate method ?
see IOleInPlaceObjectWindowlessImpl && CComControlBase for details

exemple:

u should have in ur header :
STDMETHOD(InPlaceDeactivate)(void);

HRESULT InPlaceActivate(LONG iVerb, const RECT* prcPosRect = NULL)
{
      return CComControlBase::InPlaceActivate(iVerb, prcPosRect);
}

and in ur cpp file :
STDMETHODIMP Cax3DPlugin::InPlaceDeactivate(void)
{
      return IOleInPlaceObjectWindowlessImpl<Cax3DPlugin>::InPlaceDeactivate();
}
