Anomalous Script behavior

[Peter Haworth]

Hi Mark,
Unfortunately, I don't recall the exact circumstances where this happened
because it's been a while.  I seem to remember it was a call to one of the
datagrid library handlers with a bad parameter that caused the handler
containing the handler to stop executing with no error message shown.  I
should have submitted a QCC report and will be sure to do so if and when it
happens again.

I can say with confidence that it was with an LC version prior to 6.7 and
that it was not related to a player callback.
