IE6 bug using IE9 script

[GoogleCodeExporter]

Using this code:

<!--[if lt IE 9]>
    <script src="http://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE9.js"></script>
<![endif]-->

I opened IE6 and it has the following error:

Char: 28214
Error: Invalid argument.
Code: 0

I don't know what the problem is but it is affecting my other javascript. I 
removed the ie7-js script
 and there were no errors and my javascript worked fine, so I know that there is a problem in this code.

I also noticed the same issue affects IE7 and IE8 (running in compatability 
view). The message is a little different for IE 8 but it's still the same:

Webpage error details

Seeing a similar error with the ie8 script:

Line: 7
Char: 28206
Error: Invalid Argument
Code: 0

ie9js g.runtimeStyle[a]=g.parentElement.currentStyle[a]
ie8js f.runtimeStyle[a]=f.parentElement.currentStyle[a]

I patched this using a conditional in line 2079:

if (element.parentElement.currentStyle[propertyName] !== undefined)
            element.runtimeStyle[propertyName] = element.parentElement.currentStyle[propertyName];

It doesn't really fix the problem, it just prevents the error from triggering 
thus allowing your javascript to run.

Attaching fixed source and minified file.

I am experiencing this in IE7 mode (under IE9), even with that conditional fix.
