Some Windows users have reported problems with parts of the Ensemble interface collapsing and failing to save while editing in a desktop browser. There is a solution for Chrome:

  1. Open Chrome
  2. Type chrome://flags/ into your browser's URL bar
  3. Search for "Touch Events API"
  4. Set to "disabled"
  5. Return to authoring

Please note that Microsoft Edge and Microsoft Internet Explorer are not supported for authoring content in Ensemble. There is no known fix for this particular Touch UI issue in Mozilla Firefox.  

We recommend that Windows users use Google Chrome for content creation and Firefox for testing stage sites.
