Yes  Recent versions of IE  IE8 or above  let you adjust that  Here s how    Fire up Internet Explorer  Click the  Tools  menu  then click  Developer Tools   Alternatively  just press F12    That should open the Developer Tools window  That window has two menu items that are of interest    Browser Mode  This setting determines the value of the user-agent header sent for every request  Document Mode  This setting determines how the rendering engine renders the page    More at http   blogs msdn com b ie archive 2010 06 16 ie-s-compatibility-features-for-site-developers aspx

You can use the document compatibility   mode to do this  which is what you   were trying   However  thing to note   is  It must appear in the Web page s   header  the HEAD section  before all   other elements  except for the title   element and other meta elements Hope   that was the issue   Also  The   X-UA-compatible header is not case   sensitive Refer    http   msdn microsoft com en-us library cc288325 28v vs 85 29 aspx SetMode   Edit  in case something happens to kill the msdn link  here is the content       Specifying Document Compatibility Modes      You can use document modes to control the way Internet Explorer   interprets and displays your webpage  To specify a specific document   mode for your webpage  use the meta element to include an   X-UA-Compatible header in your webpage  as shown in the following   example    lt html gt   lt head gt     lt  -- Enable IE9 Standards mode -- gt     lt meta http-equiv  X-UA-Compatible  content  IE 9   gt     lt title gt My webpage lt  title gt   lt  head gt   lt body gt     lt p gt Content goes here  lt  p gt   lt  body gt   lt  html gt         If you view this webpage in Internet Explorer 9  it will be displayed   in IE9 mode       The following example specifies EmulateIE7 mode    lt html gt   lt head gt     lt  -- Mimic Internet Explorer 7 -- gt     lt meta http-equiv  X-UA-Compatible  content  IE EmulateIE7   gt     lt title gt My webpage lt  title gt   lt  head gt   lt body gt     lt p gt Content goes here  lt  p gt   lt  body gt   lt  html gt         In this example  the X-UA-Compatible header directs Internet Explorer   to mimic the behavior of Internet Explorer 7 when determining how to   display the webpage  This means that Internet Explorer will use the    directive  or lack thereof  to choose the appropriate   document type  Because this page does not contain a    directive  the example would be displayed in IE5  Quirks  mode

The 1st element as in no hard returns  A hard return I guess   an empty node element in the DOM which becomes the 1st element disabling the doc compatability meta tag
