I have a wireless, trackball mouse from Logitech. It intermittently "freezes" the cursor on my screen. What is happening? Do I need a new Trackball? It will sometimes restore cursor motion if I gently (or not) jar it on the table. I am running Win 10 with the latest upgrades. I have an Athlon 845 Quadcore 3.5 Ghz CPU, 16 Gigs of RAM and am using 64 bit OS. Am I crazy or just uninformed?
