Cursor with optical mouse frequently won't move on screen
My cursor is 'sticky'. Frequently it won't move at all, then works normally for a while. I have the Logitech optical mouse. I put in fresh batteries, also to my Logitech keyboard, but it didn't help. I usually use the mouse on a black desk mat, and sometimes it helps when I put in on a white background, but I often have the same problem there. Can someone help me with this?
