Comeback to DAW, one 2nd instance, play with it.Switch to youtube, forum - forget about Ableton for ~30 minutes.Forget about Ableton for couple of hours.Open Ableton for sound design session (not busy project - basically empty).
The white one i opened because i wanted to tweak preset settings. And the white one which hangs out for ever. You can see the one colored ANA2 instance that was working. Please note that i use custom skin (my own modification of only 1 png file.)
