Till version 9.2.1, lights-out option on double monitor configuration, dimmed just the monitor that was assigned as main one in the OSX preferences pane. Now it dims the LR module window, no matter the screen it is on. It was very useful to have e.g. the develop module on the screen that didn't dim and the grid of pictures on the one which dimmed, so I could check white point, black point, colours, etc or just see the pictures on a blank background without any distraction. Please either bring back the old setting or give the chance to choose which window to dim.
I tried to post this on the feature request community but it's impossible to log in (neither fb, google o "get satisfaction" signin work).
