16737	prototype 1.6.1 in WP3.1 broken in IE6-8	mpol		"Prototype.js is broken in Wordpress 3.1.0 when used in IE6 to IE8. It gives a script error on line 4821:
    var nodes = $(element).getElementsByTagName('*');
The error is that this method is not supported by this object.
I changed that line to:
    var nodes = element.getElementsByTagName('*');
And now it runs fine in IE6-IE8

I'm definitely no guru with javascript, so I'm not sure if this is the preferred fix.
I also tried using prototype-1.7, but that gave the same error.
