Using Windows XP and Office 2007

Have installed the necessary components for the instant search, and it is
working fine. One of the computers on which this was installed displays a
new icon that looks like a magnifying glass in the system tray. The second
computer in the office on which this was installed and on which the instant
search is also working, does not have the magnifying glass icon in the
system tray.

By the way, is it still called the system tray? I'm talking about the lower
right corner of the task bar at the very bottom of the screen.
