Logic Pro 9 No waveform for audio in Arrange

[honeychrome]

Hello-
Suddenly Logic isn't drawing the waveforms for audio tracks in the Arrange window. Actually I can see it drawing when recording, but when I stop the waveform disappears (but I can see it in the sample edit window). Suspect maybe I inadvertently turned something off, but can't figure out what it is. Suggestions?
Thanks

If the signal is low enough it may not appear on the regions in the arrange. You can amplify the waveform display if you need to, similar to Pro Tools. Click the waveform button near the horizontal zoom/scrollbar for the Arrange Window. You can also click-hold to adjust (drag) between max and minimum displays.

No, its not that.... The waveforms for older audio tracks are there, just not for any new tracks I record...

Are you using take folders?

I saw this once, and it turned out that somehow the Record Delay setting in Audio Preferences had been set outrageously high.
