title: FreeTextBox duplicates pasted content
body: <p>I am using a FreeTextBox:</p>
  
  <pre><code>&lt;FTB:FreeTextBox ID="txtFreeTextBox" RemoveServerNameFromUrls="false" ToolbarLayout="ParagraphMenu,FontFacesMenu,FontSizesMenu,FontForeColorsMenu|Bold,Italic,Underline,Strikethrough;Superscript,Subscript,RemoveFormat|JustifyLeft,JustifyRight,JustifyCenter,JustifyFull;BulletedList,NumberedList,Indent,Outdent;CreateLink,Unlink,InsertImageFromGallery,InsertRule,InsertTable|Cut,Copy,Paste;Undo,Redo,Print" runat="Server" Width="100%" BackColor="239,239,240"ImageGalleryUrl="../../ftb.imagegallery.aspx?rif=Public/RootImages/&amp;cif=Public/RootImages/"&gt;
  &lt;/FTB:FreeTextBox&gt;
  </code></pre>
  
  <p>The problem is that when I paste into it, it pastes it two times. Is there something to solve this?</p>
