This is a (very low priority) minor bug actually, just for reporting sake:
Everytime you alt+tab from the game, then get back to it, main "enter" key stop working. Numpad "enter" key still works fine. Only fix is to close game and start the game application again.
No idea of why it happens. Never seen anything like it. It happens since earlier builds of 2.3 (never tried 2.2).
Obs: I'm using Windows Vista and Portuguese (Brazilian ABNT) Keyboard Layout, but I doubt it matters. Anyway, ppl using different keyboard layouts may test this to see if it's the case.
