I've just got a Logitech Performance MX mouse which is working perfectly under Snow Leopard, but I've noticed that the green battery LEDs keep lighting up every few seconds. According to the Logitech site, they only come on to indicate battery life when you turn the mouse on, then they go off. I've turned the mouse on and haven't turned it off yet, but the lights flash on and off. The wireless connection is fine and hasn't dropped, I have the latest Logitech Control Center downloaded from Logitech, and the battery charge is good (although I haven't charged it yet, it came fully charged out of the box). Anyone had a similar experience?
