AnaWin3 shuts down, it should call the UnRegisterAsClient
method, passing the client ID
value, then close it reference to the server.
The client’s shutdown method should immediately close its
reference to the server.

NOTE! The client should not call UnRegisterAsCli-
ent from its ShutDown method as this will
cause an ACTIVEX deadlock situation where
each process is waiting for the other to return
from its message call.
