********>Bugfix 36:
Author: Ross Walker - Reported by Dan Kidger
Date: 07/09/2007

Programs: sander

Description:  It is possible that nonperiodic simulations could switch to
              using a less efficient list building routine when in fact the
              more efficient grid pointers method would actually be more
              appropriate.

Fix: Apply the following patches to src/sander/nonbond_list.f
