Seems to me that the xy screen, in the Hot and Deep programs in version 4, is not as stable as it seems to be in version 3.2. In 3.2 when I hit a coin the line was very solid. Now, in 4.0 when I hit a coin the oscillating effect is more prominent. Almost as if it were a bottle cap, not a coin. I don't feel very confident using the xy screen in 4.0 as I did in 3.2. Anyone else notice this?
