Text cursor when over tree item

I’m loading data to the tree via XML, almost everything is working great. However, when the cursor is over a tree items text, it shows the vertical text cursor, like it’s over a text input. This is only in IE (9), in FF it shows the finger pointer. Examples running in IE show the finger pointer too, so I must be missing something. I’ve reviewed the example source and can’t figure it out. Thanks for any assistance.

Attach, please, screenshot or demo of your issue - can’t reproduce it.
