IE10 on Windows 7 Sys.WebForms.PageRequestManager.getInstance() gets exception


  • I know a similar issue for IE10 on Windows 8 was resolved, but I am still getting a null reference exception when the following line gets executed:

    var prm = Sys.WebForms.PageRequestManager.getInstance();

    The ScripManager is defined before the above line gets executed and the site works in all other browsers. 
    Is this an IE10 bug? 
    Is there a way to work around this?
