We need a “modal when called” behavior where the VI is NOT modal when the VI is not currently running (being called). Otherwise, accidentally opening the VI during development while the main VI is running will make it so you can’t interact with any other front panels, block diagrams, or any other LabVIEW windows; and you’re stuck — you have to kill LabVIEW from task manager or cmd.exe (taskkill /f /im LabVIEW.exe)
My work-around is to add this little snippet of code that uses a Floating behavior in development and a Modal behavior in a built application (EXE).
