My final solution to this, was to go into the cfwindow.js file in the application server and change the shadow attribute to false.
This will need to be replaced twice, as this statement appears twice in the file.
Note: A down side to using this method is that you'll have to redo this every time there is a server upgrade. Also, in order to use this method you have to have the ability to actually edit this file, which for users on a shared server is unlikely. Have better solution? I'd love to hear from you!
