    I have a MacBook Pro that is a few years old and just the other day the mouse started to act up. As I use the computer, the mouse gradually becomes more and more sensitive to the point where when I try to scroll, it just pulls down a menu as if I right-clicked, or it begins opening whatever files I scroll over at the time. Also, the click function does not work (it doesn't even click down, but acts like the rest of the mouse pad)

    If I shut off the computer and restart it a few minutes later, the mouse works fine again, so I am thinking it is some type of software issue? Unless the battery heating up has anything to do with it?

    The computer is no longer under AppleCare so I would rather not take it in to get fixed unless I absolutely have to.

    Is your mouse several years old like your MBP?

    If so, change the battery and see if works OK again....

    Also, can check Mouse preferences in System Preferences....

    I should have been more clear and said the trackpad, not an external mouse, is having issues. I think I have figured out that it works fine when the power cord is connected, but when I am running on battery it has problems.

    Depending on your model, if it's the unibody, you can pull out the battery and adjust the screw tension underneath the trackpad. If it's too tight it won't click, or too lose can cause problems.

    I've seen a few Macs have this problem and tightening the screw has solved the issue. If this doesn't work, the trackpad will need to be replaced.
