I have another bug with the same cause. Text does not display itself 
properly in ObjectExplorer; it shows the string but not the IV runs.
The cause is that Text is a subclass of SequenceableCollection which 
overrides each and every bit of essential collection behavior (at: at:put:, 
size, etc), a good example of proper OO design? No doubt this class, unless 
reparented , will be good for many mysterious bugs for the years to come;)
