Messages App on Macbook Pro is unresponsive
I can open the app but when I click anywhere on the window, the appearance remains unchanged. It is seemingly unresponsive. However, I can still technically send messages. If I type something and press enter, the message is sent and shows up in my iPhone messages app but not on my Macbook.
When I put it into full-screen mode it gets really funky and/or just turns black.
I have shut down and restarted my computer and the app with no luck.
I did update to the new OS system a couple of weeks ago, but I haven't had any problems until now.
MacBook Pro, iOS 10.1.1, v 10.13.3
