Deleting groups of emails with auto-preview

[PCSupport]

I have a user that in Outlook Express he could hold down his shift key and
start scrolling down and each email would show a preview as he scrolled down
to determine which emails he wants to delete. I have upgraded him to
OutlookXP and when he holds down the shift key and starts scrolling, just
the first email is auto-previewed. Anyone know of a setting that would allow
him to preview each message as he highlights and scrolls to the bottom?

Thanks,

Kevin
