Geoff:
(1) I have already suggested that Dumbledore was having a leg-pull at 
Karkaroff's expense in GOF as he was aware of the fact that others, 
including Harry. were listening as well. And /if/ it is the Room of 
Requirement, I cannot believe Dumbledore when he says: "only this 
morning, for instance, I took a wrong turning...... and found myself 
in a beautifully proportioned room I had never seen before containing 
a really rather magnificent collection of chamberpots. When I went 
back..... the room had vanished." (GOF "The Yule Ball p.363 UK 
edition).

Why? 

More canon:
"'Dobby knows the perfect place, sir!' he said happily. 'Dobby heard 
tell of it from the other house-elves when he came to Hogwarts, sir. 
It is known by us as the Come and Go Room, sir, or else as the Room 
of Requirement!'
'Why?' said Harry curiously.
'Because it is a room that a person can only enter,' said Dobby 
seriously, 'when they have real need of it. Sometimes it is there and 
sometimes it is not, but when it appears, it is always equipped for 
the seeker's needs. Dobby has used it, sir.......... 

...and Dobby knows Mr.Filch has found extra cleaning materials there 
when he has run short, sir'" (OOTP "Dumbledore's Army" p.343 UK 
edition)

How come the house-elves and Argus Filch know about this room and 
Albus Dumbledore doesn't?

(2) I agree with the comment above about Harry' return to the Mirror 
of Erised and have already suggested that it wasn't in the RoR 
because Harry wasn't looking for it and when he returned, he didn't 
go through the routine outlined by Dobby.
