Over the past week and a half, we have received limited reports of users seeing a black screen when loading the Access 2013 simulation. We have found that zooming the browser to a value other than 100% was causing a problem in rendering the simulation that caused the Access 2013 module to load incorrectly. The problem seems to be related to improper font measurements within the Flash Player plugin. As of 3:00p EST, we have deployed a workaround that returns the Access view to normal.
