Woohoo! I finally got one! I was so excited I had to join the DIS boards just to let you know!

(I've been reading them for over a year.)
It doesn't popup another window so I'm certain that popup blockers will not cause a problem.
Here is exactly what I did:
1) Start the game, see the Yes/No Hide-n-Seek screen
2) Hit F5 to refresh the window
3) Click the Play button
4) If I see the Yes/No Hide-n-Seek screen, I hit F5 and repeat until I see the wardrobe circle!
I thought it would be fun to count how many times I tried but it turns out to be pretty darn depressing. I did it 3868 times before winning!

I'm not joking. Good luck, but you have to be very patient and bordering on OC disorder to win!!!
