Bill, I am not sure if you know you can highlight any of the programs you want to end task, either by the down arrow on your keyboard or the mouse, and then end task on it. Unticking in config is not something I know if works or not. All I know is I am pretty darn sure that ending task on go back totally closes it. But I could be wrong. It could be that some programs are made to be very persistant. But its not likely.
Maybe the question to ask is "is go back" that important to you. And is there a similar program that will substitute go back
