I got an answer on this from someone at NI the other day, but I'm only now trying to do it and want to make sure I recall correctly.I have some AF actors that are subpanels in a user interface. I need to pass each one a reference to the main panel that loads them; how should I create that reference? I was using the "This VI" constant, but apparently that's a volatile reference, and it was causing the application to crash with random "Not a Refnum" errors. So should I drop an unwired Property Node of type VI and use the reference that comes out from it? Or should I drop a Static VI Refnum of the main Actor Core.vi and pass that into the subpanel actors? Which is best for a shared reentrant VI like Actor Core.vi? And do I need to close the reference from a Static VI Refnum constant when my main VI exits?Edit: Added code to accompany a reply below.

So far I don't have any problems with this solution. But will let you know, if I get some

Good luck. 😉
