Hi
I am presenting the same photo for 10 consecutive trials using a conditional loop. The task requires finding some item (photo) shown on top of the initial photo by clicking on its location. Each time it is clicked, the screen jitters. How can I avoid this jittering? 
Thank much

You need to set /erase = false.
