title: Unable to get value of the property 'getWindowInformationInternal': object is null or undefined in CRM 2011
body: <p>When I'm going to save the new Service Activity record, it will ask to Schedule the Activity and I clicked on 'Schedule' button.
  If I logged-in to server through Remote Desktop Connection, its giving following error message:</p>
  
  <blockquote>
    <p>There was an error with this field's customized event.</p>
    
    <p>Field:crmForm</p>
    
    <p>Event:onsave</p>
    
    <p>Error:Unable to get value of the property
    'getWindowInformationInternal': object is null or undefined</p>
  </blockquote>
  
  <p>And I could see the JavaScript URL in IE debugger is: <code>https://orgURL/_common/global.ashx?ver=-1654397298</code></p>
  
  <p>But it works fine when I access it from outside the server(both are IE-9).</p>
  
  <p>Can any one help me to fix this?</p>
