title: Ajax Error when Developer Toolbar is open in Chrome and IE
body: <p>I am facing an issue when click on any button in a web page after opening developer tool bar, getting sometimes ajax error 737 and some cases 500 internal server error. After that I need to logout from web application and login again back in order to work all the buttons properly. Again if I open developer tool 
  bar I will get the same error. In Firefox it's working fine.</p>
