It's old as Lemur says. I used to be able to make her switch as I wanted but today she insists on going clockwise even after I decided the shadow definitely says counter-clockwise, women... I also blame that I just got up, my brain doesn't have an SSD yet so it needs a while to boot usually.
Also left-handed.

Edit: She switched, numerous times. If I look at the legs, it's always clockwise, despite the shadow telling me otherwise. I can only make her go counter.clockwise if I do not focus on the legs and look at her shoulder with the legs in peripheral vision. Focus on the legs again and there she goes clockwise again.
