    i fail to see the importance of this.  the hide window option is primarily
for preventing full screen applications (particularly games) from crashing
or switching to the desktop when another user messages you.  i highly doubt
the hide window option is intended for any security purposes.  if you're
conserned with people viewing your screen, lock it with a screensaver or
nt/2k/xp "lock" feature.
