This is really good point!

Unfortunately, it brings me back to the question I formulated at the beginning of this thread.

I just changed the method to be

 IF VARTYPE(m.tcMode) = 'C' AND m.tcMode = 'Close'
       lcQuestion =  "You have unsaved changes. Do you really want to close this form without saving?"
    ELSE
       lcQuestion = "You have unsaved changes. Do you really want to cancel them?"    
    endif
	if messagebox(m.lcQuestion,4+16, 'Cancel Changes') = 7 && No - we want to save changes
		if not thisform.save()
		    llReturn = .f.
			nodefault
		endif
	else
	...

which I guess it still bad. Since the default choice is 'Yes', it means we don't want to save changes.
