Only one of those demos works for us - the one using client 4.3 alpha 2.

The other two versions fail in the same way that our application fails. Am I right in thinking that 4.2.2 is the latest client release? I'll try upgrading the client to see if that makes a difference.

Unfortunately we don't have a demo available to demonstrate the problem. Is there anything else we could give you that might help, IE settings, source code etc?

Thanks,

Richard
