3ds Max skin Modifier not updating unitll frame is changed.

Hey guys, I'm trying to do a 3ds max biped animation however the skin on the biped doesn't update its position to match the bone until I change the current frame. Does anyone know how I can make it update as soon as I move the bone?

Thanks
