'last category' is not expandable

[ataraxs]

Hi,
first a big thankyou for your wonderful app :-)
During a first visit, and starting from 'single cells' to 'primates', I'm unfortunately not able to expand the last descendents at the right side of my screen, when I want to expand e.g the descendants of 'Sifakas/Propithecus', or the descendants of 'Fork-marked Lemur/Phaner', etc.

Keep up your good work!
Best regards

Oh do you mean it won't let you scroll into place to see those cards on the right?

Which browser are you using?
