Anyone else seeing screwy behavior with the mute in the new mixer? Below is an outline of what I am seeing,

1) I click S on one track to solo it (any of the first 5 tracks; I didn't test beyond those)
2) all other tracks are muted and their M (Mute) button is indented and blue
3) start playing the song
4) click the Stop button
5) all tracks that were previously muted stay muted but their indented blue button changes to outdented red

Am I really the first person to notice such an obvious mixer issue?
