Script editor in read only mode

I´m not able to edit the python-script. The editor tells me it is in read only mode. Is there a way to change it?

@armin Can you reproduce the issue? What steps do I need to take to repeat the bug?

I only open the new inserted python and I´m not able to edit anything…

I suspect the error message on the script component might give a clue. What does the error balloon say? Note that the editor status bar says “Plain Text”. This normally happens when Rhino failed to load python 3 for any reason. Component will let you see the script contents but not edit them since the language is not available.
