hi @wim , this happens to me every so often, that when open a phyton3 or script node it doesn’t execute fully, it stops on loading the default template it seems. I need to close rhino to fix it, deleting the node and retry doesn;t resolve it.
@crz_06 There seems to be an occasional issue with the text control at the center of the window where it shows the code. See the thread below and check if any of these steps helps avoiding the problem. Please make sure all your Graphics drivers are up to date as well.
