The extension is really useful when dealing with Python objects. Unfortunately some functions, like 'Run Python Code' are not working for Python objects which are using the CPython engine.
Setting the engine of the shell to CPython has no effect on this behavior.
Easys way of reproducing the behavior:
Set shell engine to CPython.
Insert Python code object. Set engine type to CPython in details.
Insert the following code inside the object.
import sys
ExtAPI.Log.WriteMessage("sys.version: " + sys.version)
Connect Python object.
Click on Run Python Code button.
