Hi Jud, thanks for your compassion! I remember (slightly) that I have done this before, but I can try it again. I'm afraid doing this to lose my favorite tracks, or will they persist? I remember that I have to delete certain files, but cannot remember where and how. I also noticed that my CPU load is very high, almost to 100% when I maximize to 44.1/16. With this resolution there are no problems, so perhaps I have to buy a new computer to make 192/24 possible. I am using an iMac late 2013 with SSD en 16GB. For the rest: I am quite happy with AS now, especially the bigger font is nice to have with my eyes!
