What kind of client API ?

I'll assume you are using TWSocketServer. Does it run in the mainthread or 
in a secondary thread ?
If events are not triggered, then something is using all cpu or blocking 
within the thread which runs TWSocketServer, or the corresponding message 
pump is blocked. Since you are multithreading, first look for interthread 
locking (WaitForSomthing API, CriticalSection API, Synchronize and such).

So connections has been accepted. SessionAvailable should trigger.

Stopping to listen never break any existing connection ! Estalished 
connections have their own socket independant of the listening socket.

Only when multithreading or windows meessaging rules are not respected.

TWSocketServer has an array property with a refernce to all connected 
sockets: Client[].
