Design Binder refuses to display itself

I'm trying to get Design Binder to automatically how up in my FeatureManager DesignTree but it refuses to honor my "Show" setting in System Options.  I set it to "show" and exit the dialog box.  No Design Binder appears.  So I go back to the System Options and it had reset itself back to "automatic".  Behavior repeats upon more tries.
