I'm trying to create a little shape generator, but struggling. For some reason, I go to "my shape generators" then create a new one (any kind, same result). The generator is created, and I can see it listed as "Cylinder" or whatever, but when I hit "edit" absolutely nothing happens. I cannot see the existing code or edit anything. If I remember correctly, when I did this before, a little window with the code and some options popped over from the left side of the window, but no nothing at all happens...
Any idea what I'm missing here?
