Many of the animations in the "Module" section are not visible in my browser. I am using a Lenovo PC with Windows 10. I cannot see them with any of the browsers I have tried - IE10, Microsoft Edge, or Google Chrome. I have downloaded the latest version of Flash Player but cannot see the animations. Do you know what I can do to make them viewable. On previous computers, I wa sable to view them. None of my students can view them either.
