Description james prochnik 2005-07-15 03:35:20 UTC
I am using IE 5.2.3 on my Mac osX 10.4.2 system

Whenever I load ANY wikipedia page, i get an Internet Explorer Script Alert message "handler could not be removed"

I asked   about the problem, and they said it may be javascript on your end.

Here is what a poster told me:

Not your browser, just some wonky javascript:

function addEvent(elm, evType, fn, useCapture)
// addEvent and removeEvent
// cross-browser event handling for IE5+, NS6 and Mozilla
// By Scott Andrew
if (elm.addEventListener){
elm.addEventListener(evType, fn, useCapture);
return true;
} else if (elm.attachEvent){
var r = elm.attachEvent("on"+evType, fn);
return r;
} else {
alert("Handler could not be removed");

It checks for a couple of event-binding methods and if they're not available in your browser (they're not in IE Mac), it pops the alert message. 
Replacing the alert with old-school bracket notation event binding ought to fix it:


Is this the problem?  Or is it on my end?

Experimental patch from bug 2001 which caused this; I've backed it out.
