Stuck in Lab

Help! I can't tell if the game is stuck or if I am not doing something? I just finished matching samples under the microscope and now I can't do anything. I see the outline of a woman glowing, but I can't click on anything. When I click the hint, it makes a noise, but nothing happens. What to do?

You can stop playing because you've reached the high point of this boring game. Also thank your lucky stars it didn't frustrate you to the point of "killing" your computer. It almost did me.
