Okay, I think Mac OS X 4.8 introduced the ctrl+scroll wheel zoom, right? This hasn't really bothered me much, until I archive and installed after a rather annoying problem with some system files a few weeks back. Now, for some reason, the combo for screen zoom has changed to +scroll wheel. It's especially annoying because of the way I position my hands on the keyboard, I accidently press a lot. I don't care why this changed, I just want to know how to fix it, because it's driving me insane.
