I was working on a setup where one monitor would hold the control VI and another monitor would just hold the indicators, only displaying instrument readouts.
I tried your approach to make a parent VI communicate with another VI on a separate monitor. Both seem to function well, and it seems that the process keeps running in the parent VI, but I cannot access any of the controls until the vi on the other monitor is stopped. It almost seems like the focus is on the display VI, when I need it to be on the control VI. I need to access the controls on the VI that opens the display VI's reference. How can I do this?
