Hi all, I just bought a Logitech v470 bluetooth mouse for use with my MacBook, thinking it would be a good way to get a real mouse while keeping away from my USB ports. However, it seems the mouse enters some kind of sleep mode after just a few seconds, and when I move it again, the pointer will jump around a bit as it wakes up. This sounds like something you could get used to, but it takes just 3 to 4 seconds of inactivity for it to go to 'sleep', and often it jumps to the other end of the screen, making the mouse next to unusable. As long as I keep it in motion, it works perfectly though. I just wanted to hear if this is a universal problem with bluetooth mice, or if I should send the mouse back to the manufacturer. I've read about others having the same problem, but most people seem to have no problems. So, is this a problem with a) this model in combination with OSX, b) bluetooth mice in general, or c) my particular mouse? PS. I should add that I'm of course using a fresh pair of batteries, and I have tried using both Logitech's drivers and the generic ones that come with OSX.
