I created an AJAX ASP.NET website. When I run the site in IE, with
debugging on, I get:
A runtime error has occurred. Do you wish to Debug?
Line: 43
Error: 'null' is null or not an object
Yes No

So I click 'Yes' to debug and choose Microsoft Script Editor. It brings me
to a ScriptResource.axd file. I didn't create this file. Here is the line
it has trouble with...
evt[i](source, args);

In this function:
function Sys$EventHandlerList$getHandler(id) {
/// <summary locid="M:J#Sys.EventHandlerList.getHandler" />
/// <param name="id" type="String"></param>
/// <returns type="Function"></returns>
var e = Function._validateParams(arguments, [
{name: "id", type: String}
]);
if (e) throw e;
var evt = this._getEvent(id);
if (!evt || (evt.length === 0)) return null;
evt = Array.clone(evt);
return function(source, args) {
for (var i = 0, l = evt.length; i < l; i++) {
evt[i](source, args);
}
};
}

Any idea of where I go from here? I didn't even write this code and I
certainly don't know what it means or what it does.

Thanks.

it sounds like you might need to check the web.config. Look at the
following thread (scroll down to httpHandlers config)
