T60: Scroll Lock Indicator not working

[yak]

Hi,

when I had a T41, the ScrollLock Indicator tool that shows an icon in the system tray when ScrollLock is activated worked fine. When I install the same on my T60 (from the T60 driver matrix), nothing happens. Installation is successful but there's no icon if I press ScrollLock (the mode is still enabled). Because of that I don't know when the ScrollLock is active.

My T60 runs WinXP SP3 with all updates. I have set up the whole system myself because the R&R partition was wiped out when I got this laptop. Still, everything else works without problems.

Any ideas how to fix this?
