sticky Need to be careful when using Modify inside Select (with DoubleClick) #Bug

Adam Richards

An eagle-eyed user has spotted that if a Modify is run inside Select using Double Click (for any Draw objects, Cornu and Bezier) and is not ended with a Space or Esc, but instead interrupted by selecting a different command, the Modify will not be logged in Undo and the altered track may not immediately redisplay but go hidden. 

This is a bug that we now have a fix for, but for 5.1.2a right now, it is good practice to always end these modifies with a SpaceBar push (or Esc to cancel).
