I have a kensington studio mouse- wireless, and I love it. The scrollpad combined with three buttons and a beautiful design to compliment my mac make the perfect mouse for me. However, I've recently noticed a bit of a hiss from it when it's in use. I know that it uses radio waves to transmit it's little mouse signals back to the computer and I'm pretty sure thats what I'm hearing. The sound is definitely coming from the mouse. Does anybody have any tips on how I can rearrange my desk or something so that I don't hear this hiss?
