What are you trying to achieve?: remove experiment from list in runner (clicking on the red minus symbol in runner
I noticed that psychopy crashes when you try remove an experiment from the list in runner by clicking on the red - symbol above. I had two experiments listed then, and it crashes when I click on the symbol. The error is reproducible.
The error message is below
