Winsock problem

[Aberf]

When a user logs in they get the "Connected to server" and Uername has logged into server messages in the output box, then after they hit okay on the msg box that comes up they get the "Connected to server" once more, and the Username has logged into server message twice more. In the server app, when this happens, it shows that they logged in twice, and logged out once, and they are on the seconds line of the list box. This only happens in runtime.
