What do I need to modify to make the video being viewed to appear in the background instead of a little box when exiting full screen???

This was the case in some older XBMC versions but the current beta doesn't allow it, as I remember some versions do/some don't

I got really excited when I saw this post because I thought you were asking the same question I need answered. Basically, all you have to do is press the black button. Either that or the white button, not quite sure.
