The online "traffic-light icon" in the system tray on one of my home PCs (XP Pro, Dell) has recently disappeared somehow. It's the tray icon that looks like a "2-signal traffic light," and which shows bright green when sending or receiving data. All I have now is the "2-monitor icon" during web-connection, which is hard to tell from if any data-packets are moving.

If anyone understands what I'm trying to explain, does someone know how to get the AWOL traffic-light icon back?
