So I've had an iMac for less than a year now; it's going great apart from some minor bugs that aren't too frustrating. But the one thing that's getting to me is the scroll ball on my Mighty Mouse--the scroll ball that is apparently so gunked up it can't actually scroll up or down. Having done some research already, I know this isn't a unique problem. And having done that research, I've also found a couple of instructions on how to clean it... but they appear to be for a previous generation of Mighty Mouses (Mice?). The one I have isn't configured in quite the same way and it won't come apart the way described/shown. Can anyone help me out with figuring out how to clean the current type of mouse?
