What are the reasons that one would use SHAKE? What are the deficiencies of SHAKE? When SHAKE (or the like) is used and you experience problems: 1)What are the symptoms of "failure"?, 2)Under what conditions does this failure occure? and 3)What is the workaround for this failure? -- ************** David N.
