sortables: dragged item disappears in certain circumstances

sortables: dragged item disappears in certain circumstances


Hi,
This problem can be seen in a file I've uploaded: sortable-
disappear.html
In my example, there's two sortables, each on separate DIVs and one of
the DIVs is scrollable. When an element is dragged from one list to
the other, it disappears as soon as you cross the boundaries of the
DIV. This happens in IE7, Fx3b5, Fx2 and Safari.
Is there any way around this, perhaps by using the zindex or
something? I looked briefly over the code and noticed an "iframeFix"
property.. does that have anything to do with this?
It only happens if the DIV is scrollable. As a workaround, I'm
thinking of using a pure javascript "scrollbar" instead of using the
browser's scrolling.. but hopefully there's a more simple solution...
Any help greatly appreciated!
Thanks,
Jamie
