Are you referring to this one?: http://communities.ptc.com/message/219565#219565
No. I did write that one. The one I am referring to is older, and was written by "Paul W", who was a very smart guy that disappeared well before the Collab did. I've attached it (IIRC, I did have to tweak this a little to get it to work with MC15. The original was written for MC11).
