Refreshing Window Problem

[ghost]

I believe I followed the directions completely, so it may be a result of a setting somewhere, but I'm encountering a problem at the end where a window is supposed to pup up an minimize, it actually popped up as a tab in my current window and didn't minimize because of that. At first, I was like, fine whatever, but I have a problem where if I'm using Safari, it will actually refresh the current page I'm on to the Amazon cart instead of the designated tab, which basically means I can't use Safari. Does someone have advice for how to fix this?
