[jQuery] disable click event while dragging (sortable)

Hello Everybody!
Does somebody know how deactivate the click event on a dragable item while dragging.
I tried to unbind the click event on start, and bind it again on stop. but the initial click (=toggle) is still fired.
Thx everybody! i hope i made my problem clear ;/
