[AccessD] Auto-Shutdown Leaves Access Process Running?

I have a database that is opened by a Scheduled Task.  It's designed to shut
down automatically using

    'DoCmd.Quit acQuitSaveNone'.

But, in task manger, the Access process is still running even though in the
application window Access is not running.

How could I shut down Access automatically so that both the Application and
the Process are shut down?

Thanks!
