I'm sorry- I was a little premature in my praise. I still have no solution. When I press Ctrl+a, I expected the whole timeline to highlight blue (assuming the a means all), and then right clicking on would allow me to normalise the audio. That does'nt happen. Instead, all the files in the library highlight, and no amount of right clicking does anything. I've also assumes that ctrl+a means control, then a.
Looking in help, it mentions the equaliser, but that's greyed out.
Cheers, Norman
