Editing a sound file

[Alex]

That was the problem. Whenever I had sections selected all of the editing options were grayed out.

I don't know what I was doing that caused this (and the help files were useless) but I found a workaround that involved pretending to export the file every time I made a selection. Nothing else would return the editing options without also clearing the selection.

Tedious, but fortunately I only needed to make six cuts and I'll not do this again for 20 years if all goes well.
