I am getting thoroughly confused. I am trying to make a (semi-simple) chat program, but it seems random which application it chooses to send it to (when multiple are open) (usually the second one opened, sometimes the first). It also doesn't necessarily send it to one in server mode, even when I changed the 'to server' and 'to client' ports! I have been (mostly) trying this on one computer. When I opened the server on one computer and a client on another, I sent a message and it gave me the error message (on the server). Now when I open another on the server computer and send something, it sends it to itself, A LOT. It doesn't give me the error, either. Can someone point out where in my code I am going wrong?
(By the way, I already know what happens when a message is sent while you are typing, I plan on moving to a normal window later.)
