Grouping an event with one or more others is used when you want them all to move "as one" If an event is locked, you can't add it to a group. hth FuTz wrote on 11/6/2003, 4:57 PM I try to avoid it as much as I can since after grouping, the audio and video tracks won't lock again if you un-group some moment later (can't change your mind...) 1
