Dang. That’s frustrating. I went ahead and changed the buzzword in my comment to “fixed” so it would not mislead others. I’m not in front of the computer now but I’m wondering if in Cubase 14 that checkbox is available in the editing portion of preferences. I hope in one of the Cubase 15 Updates this gets resolved for you.
Thank you both for your replies!
