Installed 1.1.9 for the Clarity update (see my other thread for that failure). I use Precision Contrast (or anything, really) and tweak some sliders. Click on “OK”. Progress bar gest about 75% across and Studio just hangs. No CPU, just hangs. Killable, but the changes are lost.
Launched from PS CC, which is up to date. I drive everything from LR CC and PS CC. Windows 10 (up to date) 64-bit.
