In a medium sized project, a number of windows open, I'm finding that the selection of a range of notes, midi track, PRV, is not accurately reflected in the Event List window.     Sonar Plat, Windows 7
 
 
I tried to duplicate it in a simple two track project, but there the selection kept up correctly: notes selected in one window were selected in the other.  
 
Just a heads up: there's something wrong ....  
 
(one very nice new feature of Platinum, perhaps related to this problem:  when you select notes or other events now, the tracks on which they are selected are highlighted in the track view. )

If it can't be reproduced, it doesn't belong here.
 
And maybe I'm misunderstanding, but highlighting/shading of partial MIDI selections in the track view isn't new; it's been around for as long as I can remember. 

Should be moved to Sonar forums until full steps to repro can be found.
