When using IE8, opentip-native-excanvas.js throws the above exception. The origin is line 1899. This is the code:
Adapter.prototype.observe = function(element, eventName, observer) {
return this.unwrap(element).addEventListener(eventName, observer, false);
};
It should probably be changed to check if this is IE8 and if so, use attach event instead. I've seen other places in the code that do this.
