Someone in Logic 9 do me a favor? Open about 5 different tracks, audio, soft synths and fill each track with some noise! Now try and use the duplicate track button and duplicate the top track, then the track that is created drag it so it's the bottom track in the arrange window. When you get it there is it a different track then the one you started out dragging? It is for me... This file was saved at one time with ReWire running.
