So:  Out of another thread, I did exactly as indicated and it works very well.  But in one instance, a section of track was converted to a track I did not select!  by a beach I got a snow track!  and when I tried to delete.. it would not delete!  because I had this problem years ago, I did what everybody has indicated in the forums:  Delete as object, delete as spline, deletes as a track, delete from the main map.  Nothing works!  so I had to delete the track in CMP, and then it is not there anymore (of course!).  This is a bug not new to us.  Very troublesome..
