title: RichTextBox font set to all lines in C#
body: <p>I changed the font of a <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.richtextbox.aspx" rel="nofollow">RichTextBox</a>, but this change does not set to all of its characters properly. Indeed there exist two font for the RichTextBox and that is not beautiful. Is there a solution for this problem!?</p>
  
  <p>This code does not work correctly:</p>
  
  <pre><code>this.richTextBox1.Font = new System.Drawing.Font("Maiandra GD", 12);
  </code></pre>
