I see your point - the other day I got the same result over and over again, 
today the same code works fine.  I'll have to remember to build "retry" 
functionality into the system :)

BTW, just to clarify what was happening the other day, the following result 
would end up with the variable 'msg' having data:

void __fastcall MyClass::ClientDataAvailable(TObject *Sender, WORD ErrCode)
  AnsiString msg = ((TWSocketClient*) Sender)->ReceiveStr();

Whereas this code would result in the variable msg being empty:

void __fastcall MyClass::ClientDataAvailable(TObject *Sender, WORD ErrCode)
  TWSocketClient* Client = dynamic_cast<TWSocketClient*>(Sender);
  AnsiString msg = Client->ReceiveStr();
