I highlight only tracks with data on them, then I load another song. When I go back to the first song, all the settings are changed.The visibility of the output also does not show. The zones for visability also do not show correctly. I set it at first to show output on right, load new song over top the other, go back to the first song (I do not reload it, it is underneath still). When I go back to the first song, all of the mixer info is re-set and it is a mess. Is there a solution?
