Hadn't thought about chucking her out and then bringing her back in to the group - nice idea and will try it next time the problem arises. I've seen no link to injury level at all and healing made no difference. But, having got out of the city and into the countryside to whack a few trolls the problem has abated and we've only had one brief outburst in the courtyard at D'Arnise keep since. I guess Jaheira ain't no city gal
Thanks for the suggestions.
