I don't think that is it. Today I had one app open and then tried to launch another. The former app kept running, but the console spit back a display cannot be found error when I attempted to launch the second. I closed the first app and attempted to relaunch it -- but it wouldn't. I kille

This just happened. I have two apps open. Both are running and functioning normally. I go to open a third. I get the display not found error. I open a new SSH session *without* closing the old one. The apps keep running, and I am able to open the third app in the new SSH session. I close

It's definitely client side. I logged into the same server on a Snow Leopard machine and did not have the same problem. I looked at my /etc/ssh directory and no modifications were made there since 2015, so it doesn't seem that Sierra overwrote anything. What I think happened is that the defa
