Thank you, having several of them in a SystemWindow is handy for
watching expressions while debugging. I can easily do  with them a
specialized 'Expression watch window'.

However the code for UpdatingStringMorph  still needs two fixes


1) Method #step

Instead of
	
    self contents: self world activeHand morphPosition printString


needs to be something like


    step
	
       self contents: (target perform: getSelector)


2) Example call in class comment should be


    UpdatingStringMorph new
         target: [self runningWorld activeHand morphPosition asString];
         getSelector: #value;
         stepTime: 10;
         openInWorld


   Cuis uses #morphPosition instead of #position
