So last night I turn on my macbook and go to use the wireless might mouse and it's acting wierd. All sluggish and laggy. It's jumping around as I move and seems to be 'behind' my movements. I look at the battery indicator and it's full. I tried several mouse pads, nothing. It was basically unusable, I had to use the trackpad just to look at the settings. I had to close the hatch underneath the mose and let it reconnect for it work. I never had this problem before. Anyone ever see this?
