http://www.stockcharts.com/charts/YieldCurve.html All of a sudden I just get this pac-man thing in a gray box, and it says 'applet notinited' at bottom of page. Used to work, now doesn't.
I tried the link with the same result you got, except the page wouldn't fully load either. Since other java applets work fine on my PC I assume the prob is with the web site.
