Outlook not marking read emails as read

[Gerri Urban]

Hi -

We have 1 computer that is doing the oddest thing,
anytime the customer reads the last email in his box,
exit's out of email and then comes back in, that email is
now marked as unread - it's the weirdest thing I have
seen in a long time. I uninstalled office XP, rebooted,
then reinstalled and applied the 2 service packs, hoping
that would fix it, but it didn't. So now I'm stuck and
was wondering if anybody out there has any thoughts on
what to do....

thanks!
