How do I scroll through fonts in Creative Cloud Add Fonts? (not AI or photoshop)

Havent got one, using a wacom tablet. Using the Wheel on the tablet does bring up the scroll bar as you suggest which I can sort of grab with pen and move but its still broken as the scroll bar disappears while dragging it ,it is significantly differant from the behaviour of  other pages in the app where it it possible to grab the scroll bar.

Had same issue here, reseting the CC desktop app brings back the scroll bar, but cant grab the scroll bar to navigate up and down. It grabs the list of fonts rather than the scroll bar so if I move cursor down thinking Ive got the scroll bar the list goes down rather than up as I was expecting. Also having opened up my web browser to write this when I go back to the CC desktop app scroll bar is gone again while CC was minimized or not the front most wndow on my desktop.
