Internet Explorer 9 (IE9) compatibility on Windows 7

Question

When i view my map web application in IE8 with Windows XP, it was displaying perfectly. When i run the application in IE9 in Windows 7 environment, it is not displaying as like IE8. 
I am using the below meta tag for setting the compatibility
<meta http-equiv="X_UA_Compatible" content="IE=IE8, IE=IE7"/>

is there any specific way to make my application work in IE9 as expected?

Please suggest me on this.

Thanks,
Gomathi

Thanks Jeff.

No luck when i was using the meta tag as 
<meta http-equiv="X-UA-Compatible" content="IE=7, IE=9"/>

When i tried by removing the meta tag and also tried to set the content as IE=7 on the meta tag, the application was loaded with the map properly, but layer's opacity is still not working in IE9.

In my application i am using Arcgis Javascript api 3.0. I observed one more problem in my map. i am displaying a WMS layer information in the form of polygons on map by setting layer's opacity as 0.5. In IE8, this is displaying polygons with black color outer border. but in IE9, the border of the polygons are not displaying for any of the opacity.

Is this a known bug in arcgis? if so, Please suggest me any workaround to set the opacity of a WMS Layer in IE9.

Please see the below code snippet which i used to set the opacity for a layer.
var layer=new esri.layer.WMSLayer(url..);
layer.setOpacity(0.5);   //working fine in IE8(Black border displaying) but not in IE9 (Borders are not displaying)
map.addLayer(layer);

Thanks,
Gomathi.
