I have designed an experiment with the builder in the last few days and it was run successfully.
When I try to start it again today, the test window itself never shows up. The test worked fine in the last few days and I haven’t done any change nor update the version in between.
When i try to run the test in the coder view, I get the following message in the output field:
File “/Applications/PsychoPy2.app/Contents/Resources/lib/python2.7/psychopy/app/coder/coder.py”, line 2530, in runFile
fullPath = self.currentDoc.filename
AttributeError: ‘NoneType’ object has no attribute ‘filename’
Can someone give me some tips to fix the problem.
I run PsychoPy v1.84.2 on a MacOS Sierra system.
Thanks in advance for any helpful hints.
