No. The receiver boots up and talks to the server but when I try to select any music (i.e. by album or artist) the hourglass appears on the receiver and the cascade of messages appears on the server.
It was pretty stable with alpha4, but did have the problem of not having "listen" mode as I have exactly two receivers.
BTW they are the rebranded Dell's, if that's of any help.

I could send you any logs if you tell me where they are located on the server. The DOS screen where the JVM is running only show the last 24 lines or so.
