For example, when I clicked “Insert Routine” and then press the space bar, the options will reappear on screen. It got problematic if I ask participants to press the space bar to enter the experiment, as the experiment would run again when participants pressing the space bar at the welcome window. Of course when I run the script using Psychopy Runner, this problem disappeared. It seems that there’s something wrong with the Builder only. I’m really new to Psychopy thank you in advance for the help! The version I’m using is v2024.1.5.
