What do you mean by hang? It works for me (on Win 7) and it doesn't hang, but it does turn SR off and then fail to turn itself back on, which is not how it used to behave if I remember correctly. That part is a bug I think but you can just put an action to turn VC back on after the set the profile for now.
If by hang you mean freeze, it's the first I've heard of this happening to anyone.
