When I have my ppc4100 on charge, even if I've "switched it off" via the power button, every now and then it powers up, then auto dims on the time out. This is OK while it is being charged or in the cradle - but I'm not sure if it does this at other times as I have the unit in it's case.

Is this a bug?

By the way, the Boxwave USB mini-sync/charger and car/mains charger units are great. The Boxwave screen protector seems slightly over-sized and can get damaged when trying to fit and not work as good subsequently.
