Okey Dokey - Don't get me wrong, I'm not complaining about this...I understand that there are limitations to what can work...but it would be good to know what we can NOT do...So in this instance, obviously we can't freeze without losing the data. Can we make them offline? I'm thinking no. On my system at least, I can't retain the data in a subproject on re-opening...but I seem to be able to reopen them in the main project. Any chance of clarifying all this stuff? It's just that I HATE tuning, and I don't want to repeat any of it.
