I have had this problem before and have solved it by taking my mouse apart and cleaning it, but this time it did not work. My mouse at random times scrolls down infinitely. I can stop it by moving my mouse wheel up and down multiple times and then it is good for around 3-5 mins before it freaks out again. Also context menus disappear very quickly and is also solve via the same method. I have replaced the batteries with fresh ones as they were low and it did not solve the problem. I do not know the model of the wireless mouse because it was a prize I got at pax east 3ish years ago. Could this be a software problem? or is it a hardware problem indicating it is dying on me?
