I purchased 2012 yesterday and worked with it on a project I had already started in the 2011 version.

Firstly, I'm confused by the solo and mute buttons. I've looked at the online manual where the explanation seems fairly straightforward, however it makes no mention of the condition where the red mute button has just a small dash instead of M on it and what that means. It seems when that is showing, the solo button can appear to be highlighted but the track is still mute ???

Also, I recorded three audio mono tracks yesterday and changed the background colours. When I started it up today, the tracks were still there but the colours had gone back to default?

Furthermore, the mono tracks had become stereo tracks just showing data and background colour in the left channel?

Any clarification will be gratefully received.
Thanks.
