I used a cloth to clean my keyboard, and I obviously touched many buttons in doing this. I dont know what I did, but now whenever I click something or type something. A little annoying computer voice talks and says everything im doing. Example, if I turn caps lock on or off, the voice says, CAPS LOCK ON, CAPS LOCK OFF. Or if I click an application it says. ITUNES APPLICATION. Its very annoying, can anyone help me get rid of this????
