I have a jQuery popup window that works in Firefox.

However, I am getting the following error message on line 1 of my html page:

SCRIPT438: Object doesn't support property or method 'addEventListener' 
popup\_1.html, line 1 character 1

The only code I have in line 1 is:

```
<html>

```

When I run the IE9 debugger, I am getting an error on something called

```
script block(1)

```

But I am not using any javascript named "script block" is this an Internet Explorer add on or something?
