Older versions of Internet Explorer are not supported by Roll20. IE11 sort of works, but the developers haven't had the opportunity to fully test it with the application as of yet. A few questions: 1. Could you elaborate on what you mean by "chrome elements"? Did you download the full chrome browser or some kind of extension for internet explorer? 2. Please go to <a href="http://supportdetails.com/" rel="nofollow">http://supportdetails.com/</a> and copy and paste the results here (but without the IP address please). 3. Also visit <a href="http://get.webgl.org/" rel="nofollow">http://get.webgl.org/</a> since that should let you know if WebGL is working in your browser or not.
