this is just a guess that it might have something to do with the administrator
on vista does not have the same authority it used to. On mine the user is admin
but for some duties I have to right click and use run as administrator for it
to work. For some installs and such.
Not sure if this is
I use Vista Ultimate on my HTPC and the damn thing keeps changing the
settings to have the display turn off after 20 minutes of no input. Very
annoying when you are watching a movie or even a TV show to have the display
suddenly turn off.
So I go into display properties and change it to "never".
