Browser errror (dojo.js)

I am using the iCalendar widget and I seem to get the following error in my browser every time I am on a screen that displays it. It prevents the drill down form from popping up when I double click on calendar entries. Object doesnt support this property or method code: 0 nodeType is null or not an object dojo.js
