I'm trying to teach older adults how to use a mouse by clicking on pictures and once they click on that image (the image only) to move on to the next block/image. However, I've been having issues where for example the second image just flashes and then disappears. I'm not sure why. Also, sometimes it doesn't show up when I enter different positions sometimes.
