Never really figured out why my code was breaking
fixed it by looking for funny things that deviated from
the sameples,  and doing various recommended safe things,
and found a few sql errors, and one by one the crashes
went away.

The new wxWidgets just seems less tolerant of little careless
stuff that is not right.
