I clicked the IEEE button but the screen came up blank, but I managed to click out of it with the invisible links that still lingered. The same or similar stuff happened for the question mark box and the CASE box. Clicking on those invisible links brought me back to the circles, but each was blank/filled with white and none of them were links. I'm thinking that this may just be due to the computer I'm using, but I hope it helps.
