What's wrong with the chasing in the backyard? Obviously we can't see it, but it sounds like play to me, play that both dogs enjoy. It maye ven tire out the basset enough to have decent house-manners inside. It seems pretty clear to me that he wants to spend time inside with the family....
Perhaps bring him inside when you have time to supervise him and teach him the house-rules, at least? That way even if the problem isn't solved overnight, you're workign toward a solution?
