I don't know what to do. My cursor is, at times uncontrollable, just locks in place or goes over to one side and makes moves that I don't initiate. Then, sometimes, several different things will flash up on the screen as if I had selected them and I haven't. Sometimes I can use the "Enter" button to get control and sometimes I can't Sometimes the "Esc" will help, sometimes it won't. I tried unplugging the Mouse and reconnecting it and it worked for a little while. Now, that doesn't help. I can't shut the PC down, when this is happening, without simply unplugging it. Sometimes, it will go for a few hours with no problem and then it starts all over again. I'm using Firefox and they have recently made updates and I don't know if it's related or not. Any input here would be appreciated. I hope to avoid taking it and getting everything removed and start all over again, as I didn't do a backup disc like I should have. As a last resort, I guess I might have to do just that. HELP.
