Every time I try to scroll upwards in Hidden Resources -- and a few times when scrolling downwards -- I get stuck after a short while and can't get any further, except by using the 'handle' or scrolling directly over that narrow scrollbar.
I haven't found any particular logic to it, except that it seems to happen most frequently among the Ab urbe condita and Orationes volumes.
(Note: I have plenty of hidden resources, probably several hundred, and, as usual, use a rather large font size.)
