title: WYSIWYG editor TinyMce settings don't work in IE9
body: <p>I use TinyMce in my application. It works great. I faced one issue that when user types something in the editor and presses enter, the editor inserts a blank extra line. I prevent this by using <code>force_p_newlines: false</code> it works perfectly in Chrome but not in IE9.</p>
  
  <p>Any ideas on what else to write in the init code for editor? I also used <code>force_br_newlines : false</code> but it doesn't work either.</p>
