I have a MX1000 cordless mouse. Ive had it for about 6 months now and its beginning to have some problems. While playing BattleField2 (and when im not playing games) very frequently out of no where the cursor jolts to the sky, as high an angle as it can go. This isnt an issue with my mosue pad because ive tested different types, so I suspect its something with the mouse. Is there anyone who has had this problem before, or knows what I can do to fix it? This is really putting a dent into my performance, and patience.
