Issue Details

I am using subpanel controls to access the Front Panel of subVIs in my application. It works in the LabVIEW development environment but does not work when built as an EXE application.

Additional Information

Since these subVIs are intended for use in Subpanels, add them to the True case of the structure, and wire a False constant to the Case Selector terminal to prevent execution during initialization. The following capture demonstrates this approach:
