I think that may have been the bug that TAC referenced to me. I didn't get the specifics of the bug, but I was told to go to a newer version of CAD due to a known bug. I just placed the order this morning. I can see the private and public interface being a problem. If time permits, I may play with shutting down the private interfaces just to see if that makes a difference. I know that wouldn't be a "real" solution, but I'm just curious.
