Thanks! Unfortunately, I usually get responses like the one above yours. Frustrating sometimes.


Don't blame the guys trying to help. As we are seeing here, this reported problem can not be immediately verified by others users. When the "developers" look at this and find it works, your problem will fall into a black hole. More times than not, the real problem is solved/identified by a steady back and forth communication here in the forum with other users. That is all BIAB 101. So play the game nice!
