Devs, 

at some point of this beta you really need to have this addressed.

I know that this kind of issue is a little bit trademark of Stardock - I recall being unable to alt+tab in GalCiv II, but it has to end.

The point of having turn by turn game is to be able to leave it at any moment when your wife is calling, or when boss come around and ask you to do something. Whenever I leave the computer long enough to have him autolock, hibernate (which is an unchangeable for me due to company policy and set to some absurd low number of minutes) the game freezes.

I have autosaves set on one turn due to that and I am reloading but this take so long, that I often just quit. 

I know I am not alone in this issue, fix that.
