Here is my guess what happens:
Due to using “wait”, Windows cannot dispatch the touch event to your PsychoPy window. Thus, windows assumes that the window is unresponsive and offers the possibility to close your PsychoPy experiment.
If I am correct, replacing the “wait” code with a while loop flipping the window until the audio file is finished should solve the problem.
Try this:
REPLACE
if time <= 0:
wait(audio.getDuration()+0.5)
else:
wait(time)
WITH
if time <= 0:
time = audio.getDuration()+0.5
timer = core.CountdownTimer(time)
while timer.getTime() > 0:
win.flip()
–> note that you need to pass the reference to your window to your function, in my case called “win”
Just a side note:
Is your experiment detecting all touches as mouse click events? In my case, only touches including a small swipe were detected as click events, but not a touch on the screen without finger motion.
Just in case your are facing the same issue, here is the solution I developed to deal with this issue:
# How to use:
#
# Replace old code, such as
# my_mouse = event.Mouse()
#
# with the complete following code:
# Ensures that also touch events without swipe motion are registered as mouse clicks in PsychoPy (tested with Surface Pro Tablets)
# Note:
# - short touch: left mouse button press, long touch: right mouse button press
# - ensure to check for mouse clicks after each win.flip(). Best practice: call win.flip() only once at the end of each trial processing loop -> Otherwise you might miss touch events without swipe motion

self._buttons[i] = 1

if getTime:
