I have a nested list structure, and I want to be able to drag and drop within lists at various levels. This works fine in firefox and safari, but in ie (6 & 7 - haven't tried 8), dragging a nested li moves things not only within the sublist, but the sublist itself.

Example here: http://marion.newlevant.com/tests/hierSortableTest.html
This uses the latest jQuery 1.4.1, and jQuery UI 1.8b1, but I had the same behavior with earlier jQueries & jQueryUIs.
