I would be interesting to have the /same/ application compiled withj the old

applications on the same computer using the same datas and the same server.

It is because you call Send immediately after Calling Connect. TWSocket is a
NON-BLOCKING component. When you call Connect, you get control back

In my opinion, the servers are not compliant with the standard. Indtead of
tweaking the component, either simply colse the connection yourself or

When you call Send, passing a number of bytes and send is not able to send
it without blocking and non-blocking mode is active, then send returns -1 to

As you can see in the docs, it is WSAEWOULDBLOCK. This not a real error in a
non-blocking environment. It just mean the winsock call would block to
execute the task and non-blocking mode has been selected.
