<!--Early preview of version 2.3 - feel free to try this out for testing purposes only--> <script type="text/javascript" src="http://orthogonal.esri.com/jsapi/arcgis/?v=2.3">

I would be cautious of using the pre-release version of 2.3 in a production environment. Instead, you may provide a hint to Internet Explorer so it chooses IE8 rendering mode by adding this meta tag:<meta http-equiv="X-UA-Compatible" content="IE=8" />
Of course, your designers might not be happy about the latter option 😉
