You're trying to make a subclass of a class that no longer exists.
There recent changes in the Morphic hierarchy were discussed in this
mail list. Please find and read those messages.<br>
<br>
Alternatively, you can use the system itself, explore it, and see
what new classes replace those no longer available.<br>
<br>
Happy explorations!<br>
