I'm on board with Dan and John.
The control used is a treeview control in geekspeak. Either populate is with a SQL statement that includes " order by [item-date] Desc" or set the sort property of the control to reverse.
I am very heavily data dependent, and just don't use II. I created a viewer link which is added into II to launch an external viewer where I sort to my heart's content.
I believe Bert has produced something call FileApp Pro that addresses this deficiency as well (but I am assuming perhaps too much here).
