Urgent question for Sonar users

[The Front Studio]

Hi all,
I was editing a guitar track in sonar, and i maximized the audio track it was on. When i finished editing I minimized the track, and the track view was empty except for that single track. I could still hear the other instruments, but not see the audio tracks that they were on!

How can I fix this??

I'm on a deadline so it'd be awesome if you could help me out, I couldn't find anything in the manual!

Never mind! Track Manager (M) is a useful button!

I always accidentally did that on 8.5. Glad they changed that shortcut on X1.
