2000 (classic) screen moving around...

Hey just got a mpc2000 classic off ebay, but I'm having some problems with the screen. They guy said he just replaced it, and it works fine, but the black screen cover is not held down at all, so you can move it around easily. Is there a piece that's supposed to keep the black part down, or is it glued?

Thanks in advance!

its glue actually. there's a little lip around the outer edge of the cover that is glued under the mpc case.

so you think just super glue should do the trick?
