[solved] impatient chimps make the screen blink

  Hi,

  I don't have Windows 8 myself, so I can't test, but my best guess is that these touches have a special meaning for Windows. (OpenSesame itself doesn't monitor key presses during a delay period.) Perhaps you open one of the system menus by touching a specific area of the screen, by tapping twice in rapid succession, or by a tap-and-hold gesture? I suspect it's something like that. Perhaps you could look at the system settings (and Google) to see if you can find something about mouse/ touch gestures.

  Any Windows 8 users that can shed some light on this? @Edwin, @dschreij any ideas?

  Cheers,
  Sebastiaan

  How dare you suggest I'd be a Windows 8 user!?

  What you might want to try, is to keep OpenSesame busy during the ITI, e.g. using an inline_script like the following:

  # get start timestamp
  t0 = self.time()
  
  # create a mouse object
  from openexp.mouse import mouse
  my_mouse = mouse(exp)
  
  #set timeout
  timeout = 5000 # milliseconds
  
  # run until the timeout is over
  while self.time() - t0 < timeout:
      # check for user input
      button, position, timestamp = my_mouse.get_click(timeout=1)
      # proceed to ignore any clicks, by doing absolutely nothing with the input
  

  Place the inline_script directly after the skechtpad you currently use, and set the sketchpad's duration to 0. This should monitor and catch all mouse/touch input, hopefully before the fancy gesture shortcuts do. Does that help?

  Thanks all. I ended up writing more of the program in an inline script and that seems to have solved it. Specifically, I moved my stimuli from a sketchpad item to an inline script canvas. I have no idea why this made a difference, but it seems to be stable now.
