Hi,
I played around with Sortable (with option "tree") in the last days.
First I thought it is working pretty well, see this example here:

In my own application it didn't worked that well. I made a screencast
that is showing two examples: The first one is the one with problems,
the second one is the one working pretty good:

You can see the "flickering" when I am in the dragging mode. I cannot
drop it easily where I want to.
The only difference in these two examples are the versions of
scriptaculous used. I am using the current version and here it seems
broken.
I have tested this with Safari 3 and Fireworks 3 on MacOS Leopard.
