That's a good point - it could well be Chromatic Aberration (I was probably using the kit lens, after all). Photoshop CS3 has a little palette of tools that deal with CA to an extent though, when you're processing a RAW file - will that work on a Jpeg image too?
And to quickly drop in something in favour of Jpeg - last year my sister-in-law asked if I'd take pictures at her wedding, mainly for the period after the official photographer had gone. I set the camera to save the pictures in RAW and Jpeg together, and that meant that I was able to give her a CD the next morning at breakfast with all the pictures I'd taken on it, so she could let me know which ones she wanted to have as "keepers", and then I processed and printed those ones from the RAW file. Both formats working in harmony there.
I'm just not an awesome photographer, so I have to rely on RAW to give me some headroom for error-correction.. ;-)
