A stack "revCursors" is already in memory.

[Bob Sneidar]

Hmmm… the global variable revSaveAsStandalone does not seem to be available anymore, or is it a global created at build time, then deleted when done?

I have seen where the version of the stack that is open AFTER building the standalone is the one in the STANDALONE! So if you continue to use the IDE or try to build another app, you will get that conflict. That *may* be what you are experiencing, although that may have been addressed in 9.6.9 or some subsequent release.

I think preOpenCard, preOpenstack, openCard and openStack. But if you do this, then you cannot use the Auto Inclusions feature. Really a bummer.
