_Launch does not destroy the app that does the launch under MF.  Control
returns immediately to that app once the launch request is registered.

TechNote 126 has all the details.

_Chain is, I understand, obsolete and should not be used (the fact that
it crashes the system has presumably given you some hint of this :-)).
