I recently loaded the v2.00 firmware to my GRD3. A nifty new feature is the ability to change ISO by pressing the [ADJ] rocker button either left (lower ISO) or right (higher ISO).

I was using the GRD3, pressed the [ADJ] rocker to lower the ISO setting, it did, and it brought up the histogram on the display, too. As I changed ISO setting, the histogram reading also changed, appropriately. I let the ISO setting I wanted to lock in, and the histogram disappeared. Very nice.

That was last night -- today, no pop up histogram. I have no idea how I got the GRD3 to temporarily pop up a histogram. Is there a setting to enable a pop up histogram somewhere in the GRD3's menu structure?!?
