Im not losing my mind, my mouse does beep! Only very very quietly, I have to hold it up to my ear to hear it, and even then it is very hard to hear. but WHY!?
My best guess is that it can be used to troubleshoot it or something? Or maybe microsoft, who made my mouse, is giving in to the film industry, where all electronic devices are always beeping, whether its a computer, a bugging device or a satellite, even though in real life it would be pointless. Like a computer, how annoying would it be to have the computer beep each time you open a new window?
