[jQuery] Problem with sortables plugin (interface.js)


Please, help! I can't understand.
I'm using plugin "interface.js" - sortables.
I have 2 dropables fields and some sortables elements.
It's works in FireFox and Opera, but in IE, once I grag one element,
next time it's can not be dragged:

Russian.
Try to drag one element, drop it and then drag again. What is wrong in
code?
