title: Android Studio not showing properties
body: <p>I am experiencing a strange problem with Android Studio 2.2.3. No matter which widget is selected in Design View, the Properties View doesn't show the properties - it simply appears as shown below. If I click "View all properties" it goes completely empty.</p>
  
  <p>How can I show the properties?</p>
