I can't believe no-one caught this one...
Since Live 3, there has been a bug whereby the title of the Live window when minimized stays what it was when the instance of Live was started.
For e.g. if I double-click Song1 and open Live, and then open Song2 in Live, minimizing the window will still show a title of Song1.
Seems to be a design issue with the way a Window object is created and managed...mayve a variable was not reset? LOL, for those geeks who know what I'm talking about.
