title: AjaxControlToolkit HTMLEditor - Won't accept full stop keypress
body: <p>After utterly disbelieving our client when they claimed they couldn't type full stops (periods) into the HTML Editor control of the Ajax Control Toolkit on their ASP.net site, I've now sadly been forced to accept it is the case.</p>
  
  <p>When you press the <code>.</code> key, and the cursor is at the <em>final position</em> in the editor nothing is added to the HTML Editor control at all. </p>
  
  <p>If there are any characters <em>after</em> the cursor position, the <code>.</code> works normally.</p>
  
  <p>If you hit <code>return</code> to enter a newline, and press <code>.</code> it works once.</p>
  
  <p>This only only occurs in IE 11, older versions of it are fine, as are Chrome, Firefox and Safari. We are using the September 2013 release of Ajax Control Toolkit.</p>
  
  <p>Has anyone else encountered this? Any advice would be much appreciated.</p>
