I switched on the computer and the mouse was positioned 2/3rds across the screen (both left 2 right & top 2 bottom). When I try to move it, it jumps back to the origunal position. The mouse is fine as I changed over to a smaller computer to allow me to access the net and post this. My main programs are on my other computer, which I cannot access due to the mouse problem.

u could try reinstall the mouse driver and check for viruses
Even a restore to a previous time might get it going.
