FYI, today I tried to run the experiment on a new computer with a fresh install of PsychoPy and it through the same error message, so it’s not specific to the computer that I was using.
However, when I created a new experiment with ONLY the textbox component in it, it worked. So I’m guessing it has something to do with the custom code that I am I running as part of the experiment. I’m going to look in there to see if anything references numpy and see if modifying it allows the textbox to work again.
