Hi Paul,
Little buggy in Local corrections. Select some rows and right click and then go to track nos, nothing happened.
Track Nos correction not working
I tried to fill manually and then correct automatically, but severe exception … booo 
Check mail with supp files.
Now tracks are automatically zeriosed there is not much for Track Local Correct to do, it might be that you want to run Edit/Renumber Tracks Nos instead.
The error is already logged as #1883 , I’ve now found a bug in jaikoz that might have caused it or it maybe due to a bug in Java itself http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6888157 so will just have to see if it disappears in next Jaikoz release.
