I have been using my track pad on my iMac for about a year however occasionally ( now more frequently) the pointer jumps to the top left corner and won't move, neither will the wired mighty mouse make it move, now also the screen goes dim and the launch pad screen comes up. As I can't get to the shutdown menu, the only option is to hold down the power button till it switches off and boot up again. This normally clears the problem, however it is happening more frequently now and I need to fix it.
Any ideas anyone?
