From memory, I think the freezing is correct -- it confirms that you have selected a particular figure in the sequence. It doesn't need to move around then -- you have selected it. (Don't click on it again! It will reset.) So then move on to the next figure and click once on that.
The problem with this game is that there are no individual save slots, so I'm unable to go back into the game and replay this section for you to double-check the requirements.
Perhaps someone who has played the game more recently may be able to figure out what the problem is here, if the above doesn't help as regards the clicking.
