Game gets stuck after tutorial 1 complete

Hey! 

 

So I've played the first tutorial twice now. But times, the second I click the upgrade button it bails to desktop. When I go back to the game I have the victory fireworks and stuff going off but nothing I click or hit on the keyboard advances it. I alt-f4 out and start again, but it doesn't acknowledge I completed the tutorial.

 

Ok, in further playing and testing, it also switches to desktop when starting a tutorial, and did the same at the end of Tutorial 2 when I bought out the opponent.
