Centering crosshair when played multiple times

[aweson]

Thank you for the response. I'm getting closer, but now when I run the study the crosshairs are still in a slightly different position each time, the first one being a little higher than the next one, and moving downwards vertically from there. Would changing the timing of the stimuli fix this issue? 

Current setup for the trial template:
"MainTrialStimuliA":{
  "type": "AFC",
  "auto_advance": true,
  "delay": 0.1,
    "stimuli":  [{"which": ["audioStim1", "crosshair", "audioStim2", "crosshair", "audioStim1", "crosshair2"], "location": [5,5,5,5,5,5]}],
  "responses": [["ResponseF"]]
},
