New clues in JKR's site don't work?

[Neri]

Does anyone have this problem too? Some of these things work, and some
don't. I had no problems with entering the phone number and with
opening the little red box in the trophy room. However, the coffee cup
in the rubdish bin and the pen in the extra stuff don't move, no
matter how much I click and drag. Also, the plant in the closed door
room looks as lively as it has always been. I thought in the beginning
that this might be because I'm using firefox, but the same things
don't work in IE. Any ideas?
