When you first enter the room, the display is locked and the lock is broken. Ewan won't get around to fixing until you walk in and find someone breaking into the display from the other side --

Hint 4
This is one of those games where you want to remove all the colored squares, but they have to be in groups of at least two before you can click on them. Read on for a step by step.
Hint 5
These puzzles need to be planned out carefully. If you end up with just one square of a color, you can't ever get rid of it and have to start over.
Hint 6
When you get rid of a set of blocks, the blocks that were above them drop down. If you get rid of a whole column of blocks, the remaining blocks fall down, then slide left to close up the gap.
