X61 Tablet Multtouch screen question

[RRHODY]

Interesting anomaly.

I have a X61 tablet with Win7 Pro installed. The stylus AND my finger work on the screen. I was trying to configure the sensitivity of the touchscreen and found a suggestion to go to Control Panel and click “Touch Settings” to open a screen for adjusting the sensitivity. I click on Touch Settings and get this screen:
“A supported touchscreen was not found on the system.”

If there’s NO SUPPORTED TOUCHSCREEN how come the screen responds to the finger and the stylus?
As the king [Yul Brynner] said “Is a puzzlement.”

Tried installing the Wacom driver?

With everything working I'm reluctant to mess around. Leave sleeping dogs lie.
