We recommend using Google Chrome or Mozilla Firefox in the course. Versions of Internet Explorer older than version 11 (or version 11 in compatibility mode) will display a blank screen when a module is launched.
If you cannot switch to a different browser, clearing the cache on Internet Explorer 11 may solve some issues. See https://kb.wisc.edu/page.php?id=15141.
Sections of the course need to launch in pop-up windows, so you may get a message to "click here." To avoid this step, look for the option to add the site as exceptions for the pop-up blocker. Check the images below for more information.
