Scriptaculous draggable onEnd

[Nalum]

Hello all,
Has anyone ever used the onEnd option in scriptaculous draggables?

It only seems to work in Firefox.

I've been trying to get it to work with IE and Google Chrome but when
I have onEnd set they wont let the draggable drop so the user is stuck
with the object on their cursor.

Thanks in advance for your help.
