Could you please post a screenshot with the pertinent Panels visible?
Curiously I could reproduce the behaviour in CS5 (12.0.4 on Mac OS 10.6.8) once, but not anymore.
And in the CS6 public beta it seems to work as expected right away.
So after tinkering, I restarted my machine and it works. bleehhh...Sorry for the wasted post.
It really was the weirdest bug, color picking with current layer set was just acting strange after a certain combination of things but it is back to normal now.
I'm having the same problem in CS5.
With current layer selected and a not visible layer of curves (contrast) and trying to pick from the current layer it picks as if the curves layer was visible.
I have attached 2 images: first trying to pick with the curves layer off (you can see that it's picking a black color where brown should be picked. Second one with the curves layer on.
After restarting Photoshop every thing work fine again. So I have assumed that the problem is vinculated with the action done before:
- Duplicate image 2 times
- Gaussian blur of 6px to the first image
- Apply image of the gaussian (RGB channel) inverted in mode "Add", scale 2, displacement 0.
- And I create a group as you can see on the screen shots.
I can reproduce this issue every time I use this technique...
Ok, I have tried it on the windows version and it doesn't happen.
