Thanks. Lot of info about compatibility.
In some case, the content of a page may change the mode of rendering whatever the doctype.
Actually, the document mode switches from IE9 to IE7 automatically, when I follow a link with target="_blank".
Seems to be a bug.
But for my users, I changed the target and it is ok. This must be known however.
