EDIT: Never mind...a little more internet searching finally answered it. Ever since my wife upgraded to Mavericks, we had a few issues here and there with messages going to random locations. Now that I have upgraded as well, it's driving me absolutely insane. When I'm at work, we tend to chat (each using AIM names) from our laptops. But now, being that messages wants all messages to be everywhere all the time, she'll send me a message and sometimes it goes to my phone, sometimes to my laptop, sometimes both. They all end up everywhere. Sometimes I type a message to her and her phone buzzes. It's complete insanity. Is there any way to simply make our messages app on the computer talk ONLY to the the other's messages app on their computer (and phone to phone), or do we need to find another app?
