So this is a minor annoyance but it is sending my OCD over the edge. I don't have any apps saved in my dock. I removed all of them on purpose so that only open apps appear there and I can see quickly what is running. Usually, when I am temporarily done using an app, I will just click the red 'x' in the upper left hand corner but the app will stay "open" in the dock. For whatever reason, the Messages app completely closes itself after a few seconds. I know it's not a big deal but it's annoying the ever-loving **** out of me. Any suggestions? Brand new Macbook Pro 13" restored from a 2009 Macbook Pro 13" that was doing the same thing. I realized the glitch carried over from the restore. Thanks y'all!
