title: Do you have to call .Save() when modifying a application setting that is bound to a control property?
body: <p>I am programming in .NET
  I have an application setting of type string.
  On my form I have a textbox. I bound the text property of the textbox to my application setting. If I type something in the textbox it changes the value that is held in the Application setting but the next time I start the program it goes back to the default value. Do I need to call <code>Properties.Settings.Default.Save();</code> after the text is entered for the new value to be saved? Shouldn't it do this automatically? Is there a way I can make it do it automatically?</p>
