On the Farm Heroes Super Saga "Invite Friends" screen I can't select anything and there is no scroll bar to see friends not currently on the screen. How can I send lives, gifts, etc?

I can tick and untick friends. If I click the mouse button and drag the mouse, then I can see more friends appear there too.

There is no scroll bar indeed.
