Sortables Safari Bug

Hi,
I am looking into JQuery UI for sortables, but unfortunately it
doesn't work in Safari. I can click on list elements and move them
around, but it will never update to their new position within the list
(e.g., the list item will go right back to where it started). I just
wanted to report this and possibly get a fix for it :) Really, it's a
compatibility issue, I think...
Thanks
Ian M
