ibook seal

Ok basically the seal that is indicated in the attached file is slightly loose on both front corners. When I say loose I mean very very marginally loose, on the corners I can move them apart and together only very slightly. It's not really much of a problem if it stays like this and has done for a few months now, but is this something that is likely to change. Is their a quick fix? I don't really wana send it away for such a minor thing. However if the whole thing comes apart that's not good...
