Huh? But I did try that, time and time again. And I did it just now, and it didn't work. I've gotten cuppit to fix room 3, though if I read you right that wasn't strictly necessary for this puzzle; I've changed the cursor to the FIRE sprite (tried it with cursor WALKTO, INTERACT and USEINV, didn't see the point in trying more, the cursor looked like fire anyway); I've loaded room 3 in the editor; I've clicked on the pool, with the cursor resembling the fire. I've done it in "objects", "areas" and the other, first sub-setting in "Rooms". Nothing happens, nothing at all!
