Shadow warning not working 9.0.3

Is it just me or a general problem?

I have switched it on in the prefs (Enable Shadow Warning) - but I can't get any blue warning up even when I turn exposure down three stops.

  Have you tried changing the threshold in Preferences > Exposure? Does it change anything?

  You also need to click the the "Show Exposure Warning" button (triangle with exclamation mark).

  Working here in v9.0.3 and v9.1.
  
  The pref (Enable Shadow Warning) has a slider. What's the value there? With '0'or '1' you may not see a warning, because the exposure slider uses a sort of compression towards 0. It usually doesn't create a hard clamping at '0' itself.
  
  And have warnings enabled, of course. The triangle with the exclamation mark in the top right button group.

  Well at least now I think David has all the information he needs to get it working. 😊

  Thanks everyone
  
  I had done all the obvious things, but your posts suggested some less obvious ones, so it's now working fine and I have discovered:
  
  - an extreme exposure adjustment does not (as I would have expected) shift the histogram three stops to the left. It drags the white point back but tries to accommodate the shadows hence doesn't bring up a shadow warning (I was doing that as a test)
  
  - if some fool applies additional black point compensation for his paper through a curve that starts at (0,4) then a shadow warning at 3 won't trigger.
  
  Thanks again!
