Here is something that is really messing me up. In previous builds the "end of turn" button was the enter key (and still is, according to the key settings on the "input" options window) but now I get "end of turn" with both the enter key and the tab key. Hence, when I press the tab key to check for another ship to manage when there are no ships left to manage, I get the next turn function, when I would rather to some other maintenance (like designing another ship, checking a planet or shipyard's work queue).
