You can install firebug for firefox and check it for yourself. I see this in the console:
Please specify a ShareThis Publisher Key For help, contact support@sharethis.com
buttons.js (line 1)
menuUL is null
[Break On This Error]
var menuLIS = menuUL.getChildren('li');
xtcMenuFade.js (line 11)
FB.init has already been called - this could indicate a problem
all.js (line 37)
Unknown RPC service: undefined
For some reason the xtcMenu generates an error. And due to the nature of javascript -> errors in js scripts on the same page can cause other non-related scripts to stop working... Check the options of that menu - maybe there is something that you need to select and the error will disappear.
