I'm noticing some strange behavior from the Highlights and Shadows brushes. I don't remember seeing this before though.
I have one H & S overall adjustment to lift the shadows ab bit.
Now I add a second one and set it to reduce the highlights but with the "Brush adjustment In" option. I adjust the brush size and I start to paint over the hot areas of the image. But nothing seem to change.
Then I zoom in a bit and now the brush turns into a hand. Even when I go back to the brick and reset it to "Brush Adjustment" the cursor only funstions as a hand.
Only if I go back to default size does the brush re-appear.
Then if I uncheck this second adjustment brick to see a before and after and then turn it back on, now the adjustment goes over the whole image instaed of just the areas that I painted.
