What I would like to know is how to close the windows like "Colony management" or "Start Port" using keyboard ? In manual Enter and Esc have description "Close current window" but the first one only ends turn and the second one always brings up the options window, a bug perhaps ?
And yeah, the Enter and Esc keys are screwed also ( pretty brain dead design, to make one key nominally do two immensely different things - close a window to go to another part of the interface, or end the turn regardless of whether or not you're done ).
As it is, there's no keyboard shortcut to close a window, and given how many stackings of windows there is, it's darn irritating and clumsy.
Looks like the user interface is going to kill my desire to play the game.
So these posts were over a year ago, did this problem ever get addressed?
