Sunroof Controls / Dome Light Falling!

[LordFly]

How the hell do you get this piece to stay up?! It was fine when I got the car, but I just had to play with it Now it won't stay up. I keep hooking in the left side, then forcing the metal side in, but it just falls back down. If I really whack it into place, I can force the metal piece over the lip, but then the whole thing slides to the right and the left side falls out
