Not firing openCard in standalone

[Magicgate Software - Skip Kimpel]

I have a project that was working fine last week but when I create a
Windows standalone and I launch a separate stack from within my main
standalone it does not fire the openCard, preOpencard or even the onenStack
commands.

Any reason why it works in the development environment but NOT the
standalone?

Looking for any advice...

Thank you,
