I am writing a medium sized application which uses a queued state machine to handle user generated events. I am having this issue where when I am running the application and click on an enum with or picture ring, an error is generated. The source of the error is always on an invoke node or property node (disconnected from control and so they use an input reference). I believe the issue is related to open VI references which cannot be reentrant, but I'm having trouble trying to fix it.
The error code I usually get is 1604.
I know this is a vague description, but maybe someone in this community has seen this issue before?
