I'm following David Nahmani's Lesson 1 in the 10.4 book (great book) but am finding that using Option + Drag to move a looped region so that only the audio file but not the loop is moved (see image from book) isn't creating a new region but just moving the existing one back. This means that when I de-select 'Loop', the entire loop on the track is gone, not just on the newly created region. I've done this lesson once before, but that was before updating to Logic 10.6, and I don't remember this happening. Have I done something wrong or is this a feature of 10.6? (By the way, I know for a fact that I haven't copied the region accidentally. I release the mouse before releasing the option key).
Thanks for any insights.
