computer cursor won't work correctly?

it sounds like you need a new mouse did you take yours apart to

clean the ball and connections did you check mouse properties

if so get another mouse.

if you cleaned it and still have the same problem mouse is going bad

it's not to expensive get a infa red mouse i've had mine for 2 years both

of mine longtech less than $30 dollars and worth it

also try your mouse on another computer same thing
