But it was doing this since new?

If I weren't so young and ignorant (I was like 10 or 11), it was probably one of those things the warranty would've covered.

Be that as it may, it's still here, and last I knew, it was still working.

Oh, well. I'll have to fix it up someday, with new plastics and stuff (could the inner bezels from a newer, hopefully less disintegrated iMac G3 be used on this old 1999 model of mine?)
