In Builder I clicked on Experiment → README… and received the following error message:
Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\builder\builder.py”, line 766, in editREADME
self.showReadme()
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\builder\builder.py”, line 825, in showReadme
if not self.readmeFrame.IsShown():
AttributeError: ‘NoneType’ object has no attribute ‘IsShown’
I was asked to inform the developers. Done.
