Paul, it makes no difference if you select left, right, none, you can still use the meter just like you did with flash. Just because you see the vertical left or right, you can still slide the meter left and release. By selecting right, you will then get the mini maps of 1 and 8, and all mini maps will be on the left side of the screen. But I have heard that by selecting none, it is possible your meter may work better.
