Multiple instance of ActiveX (Threading related)

I created a winsock activeX control. This ActiveX uses TCP protocol to connect server.

On the same PC more than 1 applications uses the same ActiveX OCX File to connect the server.

In OCX File, Winsock controls LocalPort property is set to 0 (Zero)

My problem is when i start more than 2 applications on one client PC, Only one application receives Data Arrival Event

Why it is so, I m using Apartment threading in ActiveX Control and project compatibility is BINARY
