I have the OnConnect member function in my meAsyncSocket class but it is

This, as I said, only happens the second time I try to connect. On the
first time I may get WSAEWOULDBLOCK, but then the OnConnect will be called
and the program will work.

Si I'm guessing that either am I doing something wrong when ending the
connection or is the server doing something wrong...

Experience have thought me that it's usually me that's doing something
wrong ;-)

So if someone can see anything that looks suspisions in the way I end the
connections please let me know!

// end connection
m_pSocket->Close();
delete m_pSocket;
m_pSocket = NULL;

Not much to go on here, but a couple of guesses...

When you call the socket Create function, try passing no parameters to
use all the default settings. Particularly, the first parameter, the
local port, is best assigned by winsock instead of by your code.

And make sure your program is in a state that it is processing messages
when you are waiting. Any kind of loop or sleep will prevent the
OnConnect from coming in.
