elem.nodeName is undefined
in Getting Started

I believe this is a bug but am not sure.
When using jtree I get elem.nodename is undefined as an error. This only happens in IE.
All my variables are named fine. I have changed them around 700 times just in case that was the problem. This is either a problem with jQuery or jtree. All you need to do to reproduce the error is create a tree in jtree and call the close_node function in ie.
The exact error is
Microsoft JScript runtime error: Unable to get value of the property 'toLowerCase': object is null or undefined
line 4569 in jquery
TAG: function( elem, match ) {
return (match === "*" && elem.nodeType === 1) || elem.nodeName.toLowerCase() === match;
},
my code is here if you are interested. my code is not the problem (unless there is a work around)
