addEvent('scroll', foo.bindWithEvent(this)) IE error

[soconnor]

line 2686: this.target = event.target event.srcElement;

The event.srcElement returns null in IE 7 which hoops the next line of code. Our quick fix was to alter the next line of code from:

if ( this.target.nodeType == 3) this.target = this.target.parentNode;

to:

if ( this.target && this.target.nodeType == 3) this.target = this.target.parentNode;

However this means that there is not target attribute on the event object for scroll events.
