It' actually preOpenBackground that's needed, not preOpenStack.  Not passing
preOpenStack should have no effect.

More likely is that your initialization is altering the message path such
that the Rev libs group is not on the card of the topstack at the time the
preOpenBackground message is sent.

If I understand your reply, that seems to be what's happening:  when the
standalone is launched, your preOpenStack handler gets its message and opens
your login window.  The first card of your mainstack never gets a
preOpenBackground, because now your login window is on top and it gets its
own set of "pre" messages.

As a workaround, try adding this in your preOpenStack handler just before
you open your login stack:

   send "preOpenBackground" to group "revLibraries"

That solved it in the other case I'd seen where this occured.
