Campaign mode broken in beta 2 - v0.2.5792

Critical bug: after finishing a game in the campaign mode, when it goes back to the menu I can only see the planet, but the rest of the menus are gone and I have to close the game by force. I'm playing on a Mac with Mavericks.

 

I can't buy stock when playing the campaign mode, so I can't win the game.  I'm not sure if I am doing something wrong or if it's a bug. 

I'm not the only one: http://steamcommunity.com/app/271240/discussions/1/618459405708882981/

 

Thanks.
