Thanks, hellsbrink. That's interesting. I just replicated the observations on my own W7 installation (Fully Windows-updated W7 Professional SP1 64-bit, for the record) but can't find a set-up option to control it.
My friend's computer was logged-on as Administrator, so I logged off as my normal user and back on as Administrator too in order to replicate it.
