WPF web browser control and javascripts

I have an WPF application with a window hosting a WebBrowser control. When I navigate it to a html site which using javascripts, it gives me the error "An error has occurred in the script on this page. And we Cannot see the contents at all.

But if enter same html site in any IE, Firefox, etc. it loads the page fine.

Why the Web Browser control has the problem and how to solve it?

Thanks a lot, Gordon
