I am not sure if this is a bug in Vegas or someting I have done wrong. For the last 3 months I have been happily working on a project with 10 video tracks and 7 audio tracks. All the audio tracks bar one are kept muted and only used to sync the video tracks from a 7 camera shoot. For each scene I would selectively mute or unmute a video track to find the right camera shot to use. This process worked fine until just a short while ago when now every time a click on a mute icon for a track, All the tracks either mute or unmute. Using the Ctrl mute also produces strange results in that it will work for a couple of tracks then muting the third track for example will cause a previous muted track to unmute. Does any one know if I have some how created some mode that is preventing the mute function from working as previously?

Many thanks
