WB disappears when SB is used. To begin with, there is a large WB (W1), in which there are 2 SB, for horizontal and vertical scrolling respectively. In this large WB will be a widget (W2) in which also is WB. And when the scrolling occurs, the category where W2 just disappears. However, when you scroll up - it returns.
I think there should be a simple way, just somewhere some checkbox I have not enabled.
I forgot to say, W2 is the child of W1 that joins it. So I’m trying to use SB (W1) for his children.
