title: WPF ComboBox drop-down (data bound) values not changing
body: <p>I bind the <code>ItemsSource</code> of a <code>ComboBox</code> to an <code>ObservableCollection&lt;MyClass&gt;</code>. In code I change the collection (e.g. edit the <code>MyClass.Name</code> property).</p>
  
  <p>The problem: the change is not reflected in the dropdown box if the <code>ComboBox</code>, yet when I seled the item from the dropdown it is displayed correctly in the selected item box of the <code>ComboBox</code>.</p>
  
  <p>What's going on? :)</p>
  
  <p>PS MyClass has INotifyPropertyChanged implemented</p>
