Sometimes it will matter where in the image you click, for you to take action on a particular object. This is the case with "Zoom". If you want to take other actions on an object, first zoom as close to it as possible (until it becomes the main object in the image, i.e. covers most of the viewing area).
Try not to click on edges or corners of objects. If certain actions generate unexpected results, simply back off to the previous frame by using your browser, and choose a different object or action.
ZOOM - get closer to an object
CUT - open the main object in the image to reveal contents
TURN - show the main object from different angle
WRITE - give more written information on the object
MICRO - show an electron micrograph of the main object
FUNCTION - play an animated GIF movie demonstrating function of the main object
HOTSPOTS - highlight outlines of objects that can be clicked.
STEREO - start showing stereographic pairs for 3-D viewing
ANAGLYPH - start showing anaglyph images (red and green) for 3-D viewing
SEARCH - choose a word, it will get you to a related location in the system. Be careful to select "nothing" again (selected by default initially) if you want to start using the navigation buttons! This feature can be used for creating links from elsewhere on the web that jump to a particular location of the cell. Read how or mail the author for details.

Paul Thiessen from University of Illinois was kind to provide me with a POV-Ray DNA model made with his PovChem program. He has a nice page with related stuff on the Web.
