Assigning homebox to front page shows anonymous users a "not authorized access" message

I realize the anonymous user should get this message concerning homebox permissions.

My issue is, I set homebox url as homepage in admin.config/system/site-info. So it is now the homepage once a user logs in. But if they aren't logged in they see a message "Not authorized to access page". I have another block of content for anonymous users until they sign in, basic stuff--about us, contact us, etc.

Is there a way to remove the "non access" message?

Sorry if this isn't a homebox issue. Love this mod.

Thanks
