I may have reported this a while ago with Sonar, but CbB is behaving the same way on occasion.
 
When you select and/or focus a track in Track View the Inspector is supposed to display the corresponding channel strip. But every now and then it fails to do so and only displays the Master channel. Eventually it behaves so I have no idea what's going on here.

Just chiming in to say I've seen this behavior too. I thought it was just me. Like you, I've observed it just suddenly start working correctly. I'm just jumping onto this thread to see if anyone has ideas. 

Click to track name at the bottom of the Inspector, and click the checked option 'Lock the Current Track or Bus' to unlock it.

Starting to think it was just me. It may only happen a total of maybe 2 or 3 times in a year.

Thanks brundle, but I have never checked this option as I never even knew it was there. Now that I do, it may come in handy in the future. In the mean time I'll just write this off as an unidentifiable/unreproducible bug.
 

Good info. Thanks!
