The map interface still freezes up when I'm moving around the map. In beta 1 it use to freeze when an enemy ship appears on the map. It's more than likely freezing for a similar reason now. The odd thing is that I can tell it's still active, because if I press one of the buttons on the interface it would make a sound and the music would change as if the screen had changed. Then I would press the ESC button and I can tell it brought me back to the map screen, but nothing visually had changed.
One time in beta 1 it was able to unfreeze when I went back to the desktop or Start screen and opened up another application.
By the way, I'm using Windows 8.1. If you need anymore information about my computer just ask.
