Exercise in futility

JK Rowling likes to leave clues on her website for her young fans to figure out questions they may have about her books. The question whose answer was most eagerly anticipated, of late, was the name of the 7th book in the Harry Potter series. The answer has been revealed. Fans had a chance to figure it out by going to the webpage.

I tried to find out the title before I read about it, but it is a puzzle only in name. There is no rhyme of reason to all the clues, is there? How is a person supposed to decipher how to open the door except to blindly click all over the place until some combination of lucky clicks gets them in? This particular puzzle is not even a test, it is just an exercise in random luck. (If there is a pattern to the clues, please do elucidate).

Anyway, for those that are still flummoxed, here are the instructions:

If you go to her home page, click on the eraser and you will be taken to a room -- you'll see a window, a door and a mirror. In the mirror, you'll see a hallway. Click on the farthest doorknob and look for the Christmas tree. Then click on the center of the door next to the mirror and a wreath appears. Then click on the top of the mirror and you'll see a garland. Look for a cobweb next to the door. Click on it, and it will disappear. Now, look at the chimes in the window. Click on the second chime to the right, and hold it down. The chime will turn into the key, which opens the door. Click on the wrapped gift behind the door, then click on it again and figure out the title yourself by playing a game of hangman.
