Hey everyone. Just picked up a Bluetooth Mighty Mouse and have it connected to my MacBook. Working great so far except for one little issue i've run into. I've had the mouse now for 4 hours and when I first got it, simply took it out the box and connected it to the MB and it ran fine. However, after 2 hours I noticed the cursor had stopped moving. I took out the batteries and put them back in and still no luck. Turned off Bluetooth and reconnected mouse several times with no luck at all. However, I noticed I could still click the buttons and the ball in the middle. I took a magazine and placed it underneath and it started working fine. So here is my question: Why was it working fine before, and now it needs a magazine to even move? My desk surface isn't that rough, but it isn't super smooth like a magazine. I also tried my old Dell mousepad and that didn't work either. Again, not super smooth like my magazine. Had a wired MM for 2 years with none of these issues. Thanks!
