*" What's shown in the photo often happens when poses made for one figure are applied to another figure."

"I would make a hand pose for the figure used and apply it after the pose that causes the break.."*

Use a premade or save a hand pose and apply it after the body pose. This has been a poser problem from the begining. Thats why they made P7 with universal pose. But I can imagine it can still be a problem on occasion.
