I did not mean to suggest you did anything wrong.
But I would contact the previous owner and ask if he installed something, or took something out.
It sounds like he rewired something, because these are seperate circuits and would not act like that without a little help from the previous owner :).
If you know what he did, it will help in isolating the problem ( and trust me, he did something).
