Here's how I managed.....lift the ball to the top border as close to a side as possible. It will stick and the ball will hang very still next to the border. Then take your cursor and "attack" the ball by bringing it in horizontally from the side, clicking as soon as it contacts the ball. You have to be quick, b/c as soon as you pass the border the ball starts to fall, but once you get a grip on the timing it works every time.
