Description

Dynamo version

2.0.2

Operating system

Windows 10

What did you do?

Edit a custom node (any custom node with python) with Python, leave python window open, go back to non-custom node workspace, save the python script. GIF Below:

What did you expect to see?

To be completely honest, I did not expect this to work or allow the changes. It was something I was curious about. I really do love the feature of having the Python window open between DYF and DYN, but I think there is something that can be in place to prevent the crash.

What did you see instead?

This crash:
