I write what you read here on an Apple iBook G4, and she's acting very sketchy the past two days so I'm taking her out to the Apple Store to see what they might know. However, if they elect to keep her, to go in for some sort of invasive process, then you may not hear from me for anywhere from a couple of days to several weeks, such is the nature of the "Genius" Bar.
I'll be back as soon as possible. Wish me luck.
