I'm trying to enable tracking changes for all, or even one, story, but it doesn't seem to be enabled in applescript.

I can set the tracking changes preferences - ie show added text, etc, but not set tracking changes enabled for all stories. There seems to be a class for setting track changes for a story that's boolean, but I cannot get it to work on an open story. There does not seem to be any setting for enabling the track changes for all stories.

tell application "InCopy"
	--this does work
	tell track changes preferences
		set show added text to true
		set show deleted text to true
		set show moved text to true
	end tell
	--this doesn't work
	set myDocument to document 1
	set track changes of myDocument to true

end tell

Can anyone confirm what I'm seeing, or point out where I may be in error?
