I have followed all advice and cannot stop the cursor from erratic jumping in
all applications. Not the mouse battery, touchpad, nothing works. I can leave
it sit untouched and watch the cursor jump randomly. All in all, while I can
use my notebook, this has been my worst Windows experience and I've been
using a PC since I met Gates in ABQ in the early days with his Altair
strapped to his bicycle pedaling down Central Avenue. Even my old Commodore
Pet was more user friendly. It seems to get worse with every Windows Update!!!
