IE7 webbrowser control and SWF/PDF files

My app embeds a webbrowser control. One issue I notice after installing IE7 is that if I browse directly to a SWF or PDF, the page is blank. If I browse to an html page that embeds a SWF, it works fine. This also works fine in IE6. Am I missing a flag/setting when creating my webbrowser control?
