Larry, yes you are in the wrong place as saving cues has nothing to do with saving edit history.

With destructive editing, when you close the program you are prompted to save if needed, and this saves just the edited main file. The temporary files needed for the undo feature are deleted, so Undoability is lost when you close the program. If this didn't happen, you could end up with huge wastes of disk space full of temporary files from long forgotton projects.

Multitrack non destructive editing just keeps lists of changes to make to the original file, which is not altered until the final mixdown.
