Can anyone think of a reason why my player would drop mysteriously into standby mode while It's sitting here playing at my desk?

I do not believe I set any kind of a timer in Hijack. The Hijack screen blanking feature was not activated. The IR remote was not accidentally pressed, and I don't have any other IR sources in the vicinity that I know of.

It was hooked up to ethernet, but I don't know of anyone on our LAN who would have known the player existed, let alone browsing to it. It doesn't show up on any internal server lists that I know of, someone would have had to go directly to the IP address in order to get anything from it.
