Question : Automatically calling an external hyperlink in Power Point 2007

I have a slide with a hyperlink which displays an external web page.

I want the hyperlink to automatically activate when the presentation reaches that slide. Now you either have to mouse-click, mouse-over, or double click.  The displayed page should also close when the slide advances.

A possible option seems to be to display a web page inside a picture box, but that does not work either.

This used to work in PP 2003, but there seems to be no "open" action in animations anymore.

Is this possbible?

Thanks
