Sound Editor tools don't show in OSX 10.7.5

Any idea as to why the Sound Panel Envelope tools do not display in OSX 10.7.5? I have Show Volume ON but when I followed the instructions in the docs, but to no avail. Are these outdated tools?

I can’t speak to your specific problem, but a great deal of STBP functionality wasn’t working for me while running os 10.7. I had to upgrade to 10.8 to get it to work properly. (running 10.8.5 at the moment)

The interface has changed slightly. Hit the Alt button while clicking on the audio file to create a control point for the sound envelope.
