... now I found out there must be something "wrong" with the "predefined" V4-handpose-files for V4... (.*.hd2 )

If I use V4 with all her MORPHS and "give" her the left-hand-parented sword (a prop) in her hand, everthing is perfect. Even with "inherit bends of parents" enabled.

BUT, as soon as I go to the "hands" library in POSER an click on a left or right hand-pose for V4, the sword starts to deform...
