I found the culprit, not the cause.
Inside the track folder, I have two tracks, the second cloned from the first. I am rather unfamiliar with this part of Sonar, so I was surprised to see that when adjusting the volume for track A, the volume on track B follows. Is this normal?
Anyhow, here is the behaviour:
I can drag and drop Track A outside the newly created folder, but not track B!!!
Having moved Track A on the outside, I now can move the folder where I want. I can then, having repositioned the folder, drag and drop Track B inside the folder again.
Something is weird. It is 100% reproducible.
If I reload the project from scratch, with both Track A and B inside the folder, then try to move the folder, suddenly I see only Track B (no folder, the other tracks are lost) and the tracks panel is "frozen", I then close the project without saving, to avoid damage.
I will not clone any track anymore, that's for sure.
Edited: I inserted a new track (Track C), moving the clips from Track B over to this one, and using the same synth as the "mother" track. Then I deleted the cloned MIDI track, Track B. Now all is good, I can move the track folder around just fine.
