[AccessD] ActiveX control keeps A2K from closing

I added an ActiveX control to my A2K application and with it in the app
Access will not close.  (My app closes, but Access itself stays alive,
and will not close for anything - I have to kill it with Task Manager.)
Is this a known problem with some ActiveX controls, or is this just
Access?
 
Otherwise the application and the ActiveX control work fine, so I hate
having to take it out, but Access not closing is a show-stopper.  If it
matters, the control is ESRI's ArcGIS MapControl control (not
MapObjects, which is another of their products).   I admit that ESRI
does not say that the control works with Access, but they do give lots
of VB6 samples.
 
I get the same results when I open the app with Access 2002.
 
Thanks in advance,
