We have been having a problem with our SqueezeBox. We normally leave it connected to SqueezeNetwork so we can listen to our Pandora station. For the past couple of weeks whenever we attempt to play a station, we would get prompted to install a new firmware upgrade.
Even though the install went successfully, the SqueezeBox keeps prompting to update the software again.
I just noticed that Logitech released verion 7.0 of SqueezeCenter (which had been called SlimServer) This version integrates the content that is available on SqueezeNetwork into the local server, so you don't have to switch servers.
Hopefully this will solve the firmware upgrade prompting.
