I have Bibleworks 8, Asus laptop with Windows 8.1. Bibleworks is the only program in which my trackpad's two finger scrolling doesn't work. I can move the cursor and click with the trackpad but not scroll. USB-mouse works perfectly, so does up and down arrow keys. What should I do?

I have another non related question. Does BW10 still change keyboard to ENGlish? I have tried to change the default keyboard layout language in BW8, but it doesn't stay.
