Hi Robert-
We have indeed been down this road before--I think I sent you a test case.
Here's our thread from the mailing list archive if that helps:
http://structbio.vanderbilt.edu/archives/amber-archive/2004/0323.php
I'll search my email to see if I can find the resolution, since I can't recall
what happened!
