I opend logic and checked again. For some reason the problem has been fixed. I did not installed the update from 2015. The only thing I can think I did lately is to install some minor update for osx and reinstall the elicenser application to the latest version. something clearly happened because now when I open dark planet and go to the presets browser it opens inside halion sonic. When I tried to do this a month ago, the presets browser looked different and very buggy. It was impossible to choose a preset. now its fine.
update: checked again… opened retro and logic crushed 
but… I’m sure something is different because the browser window.
