How to edit VI in a library?

[Benoit_Provost]

I downloaded the example Vi library "Sine Swept Frequency Response", which contains a VI showing how we can get the frequency response of a filter. I would like to integrate this functionality in my own VI. However, when I start the VI, I get no editing menu. I cannot see the diagram and modify it. Is this protected against editing. If so, why?
I attached the library to this message.
Thank you,
Benoit Provost

The edit menu and diagram are there. The VI is set to hide the menubar and toolbar when running but all you have to do is click the stop button.
