If I select a Custom set of shooting parameters, C1, C2, etc., and override them during a shooting session-aperture, ISO, white balance-and then turn the camera off, when I turn it back on everything is reset to the Custom setting I last saved when I set it up. That's to be expected. But I lose any temporary overrides after the camera wakes up from sleep mode, making that mode useless. Is there a menu option that fixes this, or is a firmware fix needed? Is anyone else experiencing this or could it possibly be restricted to a specific camera? I've got Firmware Ver. 1.1 installed.
