One other thought... If your box is using Vix, the default behaviour for an enigma 2 crash is a full gui reboot. For example, I missed around with my Autobouquets configuration a few weeks ago, when ABM ran early in the morning, it would crash the OS, cause a reboot and hey presto, it's switched on without me doing anything. Once I realised what the crash was, I fixed it and no more issues.
