Machine is a Win7 Ultimate 32 PC, dedicated to all my automation drivers. I think it's an I5-661 CPU, Gigabyte UD4p motherboard. 4 GB RAM. Using a free Pandora account. Software is the latest Nuvo Configurator Software + newer Autonomic Mirage software (latest as of a few months ago anyways).
Usually I get between 1 to 3 days before it messes up. "Stability" was perhaps the wrong word to use; I'm not seeing an actual crash. I'd guess it's about connectivity. Once Pandora has been initiated with the MusicPort (Assigning a Pandora radio station to at least 1 source), after a certain amount of time, I'll get a message on the GC keypad along the lines of "Connecting to Source". It'll just hang there, and I won't be able to access MusicPort functionality anymore for that source, or possibly for all MusicPort sources. Sometimes it happens right in the middle of a song being played; particularly worrisome when we are entertaining guests!.. Anyways, it's almost like there's some sort of brief loss of connectivity when it's streaming songs, which the driver doesn't gracefully/quickly recover from. It's specific to the Pandora functionality -- for the past couple months I gave up on Pandora entirely and was just using MusicPort to play Windows Playlists and I didn't hit the issue at all.
