Yet another drag issue... not working in IE, PERFECT in Chrome, OK in Firefox.

Tryin' to do this without using the UI plugin... I have another variation working on a table.
Here I apply it to a select and its options.
Works perfectly in Chrome, OK in Firefox (highlights text when you move downward), and not at all in IE - despite various hacks to handle both the default behavior and IE specifically.
I should mention that this code was adapted in part from http://www.lukedingle.com/javascript/sortable-table-rows-with-jquery-draggable-rows/#more-190 whom I have to say THANKS for getting me as far as I did with my table...
Any ideas?
