.. I am unable to adjust it for a custom setting? I can get the + side to highlight in yellow.. but the yellow arrow remains on the - side ..and the number in the center (0) is unaffected by no matter what I touch? * ...'maybe in aperture priority mode it locks you out? I am always late to the party. I have only had this for one week. Thanks. Jim * pressing that Up/Down bar gets you an interesting screen...?
