Kano Startup Issue- Click on the Circles is hanging

[thwaiteschris]

I've just sourced a used Kano raspberry pi 3 kit, which my son is very excited about.

We've put it all together, and it's working and booting fine, but in the start-up routine we're struggling to get past the mouse setup.

We get to the screen saying "Look... an arrow! Use it to click on the circles"

My mousepad and click button are definitely working, because I can click on the circle, and I see it "explode".

At that point I'd expect to either be able to move on, or to see another circle appear (because the prompt says "circles").

But neither of those 2 things happen. I'm just left hanging on the screen with the "Look... an arrow! Use it to click on the circles" prompt, and an animation showing a pointer on the trackpad then a pointer on the click button.

Any ideas?
