Hi Kieth I just checked my copy and it seemed to do what it seems to do. I did get list out of bounds notice but no other problems reported. One thing, I have a full copy maybe that is the difference or maybe it has to detect an internet connection. Other than that raise a support ticket.
If the go button is missing I would try reinstalling the Editor. I tried everything to make my go button disappear or be greyed out including turning off my WFI but the button was still there available to click.
I can't hear what I'm looking at.
It's easy to overlook something you're not looking for.
