I have problems with the task above.

Delphi 2007, ICS 5.25

TwSocket used with UDP protocol to send data

At runtime I use this code to switch to another Addr/Port:

until MySocket.State = wsClosed;

MySocket.Addr := NewAddr;
MySocket.Port := NewPort;

MySocket.Connect; // All good until here

MySocketOnSessionConnected is only triggered if Addr and Port have
really changed. It is not triggered if the user leaves the values as
before (I know I can handle that).
In both cases trying to send data results in an "Socket is not
connected" exception.

What's wrong here?
