Dynamo version

Operating system

What did you do?

  • I was editing two python scripts, one insides a dyf, one in the main dyn.
  • I left the modeless dialog up from the python node in the main dyn file, then started editing a custom node dyf, and a python script inside the dyf.
  • I had the two modeless python windows up next to each other, to compare the two scripts.
  • i did not edit anything in the dyf, simply closed the inner python, switched back to the main dyn tab and tried to save the outer python.
  • Dynamo entered crash protection with this warning:
