Hi, Ed,

The error you are receiving isn't related to your adding a system variable to a spec, it occurs each time you File | Close or 'x' out of the specification.

I've reported this to R&D for you.

As you may know, the spec editor within PO is different than the one used in other Adagio modules. We are working to make the program more Adagio-like; however, this will take time.

In the meantime, I recommend you use File | Save whenever you've made any changes to a spec. After, you can either File | Close or 'x' out of the spec and, when prompted to save your changes again, say 'No'. This way, you won't receive that access violation error.
