Seems like "Keyboard" unit under Def+ "items to monitor" is not on friendly terms with certain trackpoints

Judge by some number of similar messages reported previously.
One of them (was reported approx 1.5 years ago): when Lenovo Thinkpad touchpoint device (hope, named it correctly) was causing increased consumption of CPU resources until "Keyboard" unit under Def+ "items to monitor" was turned off (unchecked).
