I am using a MacBook with Mac OS X 10.4.11. And I am facing a serious issue with its Trackpad. From the last week onwards it is not working completely. Therefore, I tried using a mouse with it. I was able to do right click with it, but not the left click, as the left click was not working at all. Though, I can use the scroll button also to click some things, but not anything in the window. So, now both, Trackpad and the mouse are not working with my MacBook, therefore I think there is some problem with my MacBook Pro. But I am not able to figure out what the problem is and how can I fix it. If anyone of you has any idea about this, then please reply.
