Thank you all for your help. The tracks are instrument tracks, nothing is hidden or soloed or locked or muted. I copied the track to a new version of that song and it can be moved-I am assuming the standard corrupted song file was the issue. I see many reports on all the Logic forums about things not working some times[and this song was started in Logic EXpress 7-I remember someone advising opening pre Logic 9 songs first in Logic 8 then save the song and it will open in Logic 9 Logic and it could just be that.
Again, Thanks to you all for the help
