OK, right out of their HELP topic page:

If a track is Stereo, you’ll see a combo box that has the following 3 choices: Edit Both Ch., Edit Left Ch., and Edit Right Ch. You can edit both the left and right channels or just one of them.

The current time within the song, if visible within the Audio Edit Window, will be shown as a vertical line in red. This will be drawn in reverse video if the current time is within the selected region.

This does not work anymore. It did in all previous versions. And according to tech support, it's a glitch.

And I use this function all the time. Well, I USED to! It's especially useful for panning effects. Gradually fading out left side while fading in right side. All in one window. Not two separate tracks.

Also, to Just Sayin . . . Thanks for the tip. But I can't find any radio button for stereo vs. mono. I went to Preferences/Audio. There is a button to select Left, Right or L&R. I can't find a "Mono or Stereo" button.

And I don't record anything. I'm talking about rendering, not recording.
