Display Waveform Preview While Recording option in Edit > Preferences > Customization - Display is selected to show waveform preview, but when recording a track I see nothing until I stop recording. What else could I have done to affect this?
Thanks if you know.

Hmmm. This is a tough one.
 
Buses have Wave Form Preview Buttons.
 
Tracks Should show the wave form preview if they are armed for record and you are recording.
 
Any more information you can share?

This is happening to me in Sonar X3e as well. I found out that if I arm record in a specific Take Lane the Preview is displayed in the Take Lane, but if I simply arm the parent track and no specific Take Lane the Preview is displayed in the Track Window, nice and big how I like it. I don't think this was working this way when I was recording several Take Lanes on a track a few days ago. Puzzling...???
