If you use "Select All" I think you need to do a selection in the timeline which excludes the empty area in the beginning, the place where you want the tracks to be moved. If you only "Select All" then also the empty area gets selected, and as the empty area can't move to "minus time", nothing can be moved. SONAR tries to move everything you have selected, not only the clips.

It would have been best to simply make a thread of your own for this question. If you add to a very old thread, it easily happens nobody finds you.

That's it! Thank you so much, Kalle! It never occurred to me that 'empty space' might be considered part of what I was trying to move, but I'll know better next time.

Thanks also for the tip regarding old and new threads. I was assuming (I do that a lot ) that the forum was ordered according to the most recent posts, so that even replying to an old thread would automatically move it to the top of the list. Again, I'll know better next time. Cheers, mate!
