IE 7 document mode in IE 8 versus IE 9
I ahve a site on my company's network and is an internal web app. I use html <object> tag to embed a pdf inside browser window. some people are upgraded to IE 9, some are on IE8. default setting for IE is to show intranet sites in compat mode which thn forces document mode to IE 7 standards. In IE 8 browser mode and document mode = IE 7, this object tag works correctly, shows pdf. but in IE 9 browser mode and document mode = IE 7, the object tag do not show pdf always. I am confused how document mode = Ie 7 can behave differently in 2 different browsers.
pls suggest if any.
