Strange database error when closing Livecode on Windows

[Peter Haworth]

Maybe.  But it doesn't happen on Macs, only Windows (haven't tried Linux).

I hope Livecode doesn't do that on any platform since it's quite possible
that applications will want to do some db housekeeping when they are closed
and this would prevent them from doing it.
