I'm hoping this is just something obvious I'm missing.
Using Save Settings from the Setup menu, I would expect the current Picture Control setting to be saved (the manual says so) along with everything else.
Well... it only does when you've set one of the built-in Controls (Standard, Neutral, Vivid or Monochrome). It doesn't save the setting if I've set anything else, in which case it always comes back as Standard.
Has anyone else come across this, or does it work as expected on yours?
