Paul,

The bug was a subtle one where the saved path event-function (and KS
trigger) designed to handle future-instantiated space instances was
being run before the new space instance was instantiated completely.
Thus, event-functions/KS-triggers were not being associated with the new
space instance.  The bug was masked by some non-optimal event-function
management code that was over-aggressive in saving path event-function
information and in searching through the saved information (which
recovered the desired behavior in some instances).

All of these issues have been addressed in a newly committed GBBopen
update that contains an extensive rewrite of the space-instance
event-function/KS-triggering mechanism.  There is a slight possibility
that some GBBopen applications may have unintentionally relied on the
incorrect path-related event-function/triggering behavior (so check
application behavior accordingly upon upgrading GBBopen).

Many thanks for the problem report!
