Hey guys, I let one of my buddies on my computer last night and he just started pressing buttons. Now when I click something a black box goes around and my computer converts it to speech. How do I turn this feature off? Also, when I click apple in the top left it has double everything. Anybody know what has been activated? This is very annoying. Its a early '08 Mac Pro, 3.0 ghz 8-core, 8GB ram.
