Working in the latest version of Ps I'm not able to use the colourpicker in de gradient editor. Not in the gradient tool editor and not in the editor from a gradient adjustment layer. I've looked and searched over the internet what could cause this problem an found this frustrated person, Adam Duff, https://www.youtube.com/watch?v=6adWgu2a58o.
I regognised his frustration and tried what he did: install an old version of Ps. Voila, now it worked well! In Ps 22.2 it worked fine, in the latest version it does not.
Am I missing something or is this a bug??
