Hacking Bubble on DS Lite top screen?

[babelfish]

So I noticed today that there was a bubble on the top screen of my DS Lite, although this is the second time I have seen it. The best way I can describe it is as if a water bubble was caught underneath my screen, and it's noticeable when the screen is on or off. If I touch anywhere near it it gets bigger, and when I let go of it it shrinks back to it's original size and makes a snapping noise. After leaving my DS on for a bit it went away, but I still have no idea what it was.

Should I be worried, or have some of you seen this too? Thanks for any responses guys

Open up your DS and let it dry. Maybe you dropped your DS in water?

i've had this too. but it was because of my top screen protector's silicon reacting with heat.
but if you mean on the screen itself, i've had a little "rainbowish" watery "film-bubble" on my bottom screen.
but i don't think this will affect anything. the screen still works perfectly =p
