When you click the widget it used to open full-screen.
Now when the user clicks the widget, YoWindow weather page is opened - http://yowindow.com/weather.
If you want the widget still to open full-screen on click, add the following parameter to flashvars in HTML code.
mini_action=full_screen
If you experience a problem with editing flashvars, just setup the widget once again on the page.
