I've finished the companions quest line, now whenever i see Farkas or his brother, they repeatedly open their dialogue boxes with me, i mean like every few seconds, its hard to get away from them also as they lock on to my char and chase her. its a glitch of some sort, anyone else got it or know how to stop it?

Also, and tied into the same chatty brothers, is the side quest to cure their werewolf side and mine too if i wish - except - well, it won't activate the cure at the offering bowl in Ysgrammors tomb, even though i've got a few of the required witches heads. the 'X' button with 'activate' shows up at the bowl of flames, but pressing 'X' does nothing - Anyone know a workaround or have i missed something????
