Disconnection from the OPC Server was created by idopc

Hi,
We're evaluating QuickOPC.
We'd like to know how disconnections from the OPC server are handled (e.g because of network problems).
1. Is there an event we can get notifications from?
2. Will the client automatically reconnect to the server when it is possible?
3. Will we still get notifications about changed items or do we have re-subscribe to these items when the client reconnects?
4. Can we unsubscribe from changed item notifications while the client is disconnected from the server?

Thanks,
Ido
