Well I didnt understand that too myself as well I just had both ith opened and the buttons were the same. Memorize what is what and then close the normal ith and do that thing. About the black screen I don't know because that never happens to me. And what you mean by windows locale?
I am using windows with japanese system locale so I can play everything without issues and not neededing any applocale thing.
I just remembered one thing too and may solve your black screen issue. When I go to the game I open the game first then open the ith alpha and start game for text appear and once i see the hooked text close and open the normal ith and do the same.
So try open the game first and see if black screen pop-up if not then do the rest as normal. Good luck :)
