I have just reloaded 10.4 to my fat frog because of this tracking problem. I was trying to programmme a chase and 10.8 would put the last cue from the playback fade into every step of the chase. i tried moving the channel fades up and down and to zero, i made sure there was no cue or a backout cue in the playback fade and YES the playback was at zero but still the software recorded unwanted channels to my chase. The only solution was to reload 10.4.
While I'm here having to tag channels when you are reprogramme submaster, WHAT A PAIN!!!!!!!!!! Give us an upgrade without tag generic channels please!!!
