I'm running 148/bin. since it was released,butuntil wed. allways had autoroll on.Somehowe with auto off on all three settings it maneaged to change keys by it's self on both providers simatainly causing everything to go black. Tried everything but cheking keys because they shouldn't change and never heard of this problem with this bin.
As 148 is a new bin with newer functions such as auto roll on/off, I change mine to an older model bin, the 146 to enter the keys manually. Perhaps it's a bug in the bin? Try changing, or not and see if it happens again.
