ActiveX/COM BrokerClient Connects but QueueLength property i

I am using the ActiveX control to create a BrokerClient and Connect to a broker
The connection looks to be successful, the only thing that looks suspicious is the value for ClientInfoset which is: “<Protocol Error (111-1433): A protocol failure occurred.>”

All other properties look valid and indication a valid connection (IsConnected property = True for example)

The QueueLength property however always returns Zero
Even though the Adapter manager shows there are many events in that queue on the broker

any one tried the same thing successfully?

thanks, Scott
