Unable to select Rabbie's lower response options

[URNMYWY]

New to the game. Most characters only have 3-5 response options, but Rabbie's 8+ response options go off the bottom of my screen. Unfortunately, I can find no way of scrolling down to the lower responses...particularly to the response that ends my conversation with Rabbie, so that I can continue playing the game. I am unable to find a solution, so hoping somebody is still monitoring these boards and can help me.

Playing without a mouse, so just a laptop with finger pad. I'll try to find a mouse to see if that fixes my issue.

Thanks!
