Superwidget affects touchscreen and trackpad on windows 7 premium home

Running a Fujitsu tablet with Windows 7 Home Premium...and waiting for the laughter to die down....ok, so running a tablet with Windows 7 Home Premium and even before booting up HogPC4 v.3.9 plugging in a Superwidget makes the touchscreen AND touchpad awful- jittery for the touchpad and only intermittently responsive for the touchscreen. Anyone else notice anything similar?
