Can't get Ultranav Tab to show up in Control Panel

[Steve06]

Hi,
on my T61 with Windows 7 64-bit, I don't seem able to get the Ultranav tab to show up under "Mouse" in the Control Panel.
I tried reinstalling the newest Ultranav drivers for my OS as well as the Utility a couple of times, in vain. The problem persists.
I've tried a few tips I found on related articles in Google, but nothing helped.

If you know about this problem and how to solve it (under a system similar to mine), I'd be glad to hear about it.

Thanks,
Steve
