Hi, I just tried to to get this to happen and could not. I tried in normal, loop, quick punch, and destructive record modes. I can't think of a preference in 6.4 that would cause this. Does this happen in all sesson or just one? You may want to trash your Pro Tools preference to see that has any effect. Let me know what record mode your in and exactly what order you are doing things in and I will give it another try. Thanks, Digidesign Tech Support
