Commandos 3 new demo: bug?

So in the new Commandos 3 demo, I was moving merrily along, until the point where the sapper shows up. There he is, standing there. Tutorial instructions say to right-click him or press 4 to select him. Neither works! He seems totally unselectable. And this kills the demo since you need him to do the next task (blowing up the tank)!

This is a bummer as the demo seemed quite fun up to that point – interface not as hairy as I’d heard previous Commandos games were…

This happen to anyone else?
