I had this mouse for almost a year now. I've really enjoyed it. I've enjoyed being able to FEEL my desktop. But now, it starting to do what my Microsoft Optical mouse did.........DIE!!!! It'll quit, and I have to unplug it from the USB port and plug it back in. Are ALL optical mice as bitchy as this? I REALLY don't want to go back to the old BALL mice, which, once plugged in, would go forever and never die on you. Why does my mouse keep dying?
