I know that real mice are supposed to squeak, but what about my Pro Mouse? I received my new iMac a week ago tomorrow, and within hours the Pro Mouse was squeaking a bit every time I clicked. By now it's gotten so that just slightly changing the pressure on the mouse by moving it causes it to groan slightly, like a door whose hinges need to be oiled. Am I the only one with this problem? Is there anything I can do about it? It's an amazing mouse, and I'd hate to have to part with it, but this squeaking is driving me mad!
