Hi list, I've installed the latest version of WebClient from the metacello configuration, and when I run WebSocket example I get the following output in the Transcript: New WebSocket(127.0.0.1:33022) WebSocket(127.0.0.1:33022) Which I guess is alright, but then if I access localhost:8080 I get the following: ConnectionClosed: Connection closed while waiting for data.
