Gregg,
Doesn't sound like you really care (nor do I!), but ColorIt! is being re-built for X, at least it was when I talked to somebody at MicroFrontier several months ago. I don't use it as much as I used to, for the same price, it's hard to beat Elements 2! But it is still a quite capable pixel (non-vector) graphics editor 'for the rest of us!' And it will open and display an image before Elements is even loaded.
Some one mentioned saving as a jpeg, opening in AW, saving as jpeg again. Just remember that a jpeg will lose some pixels/info with every save. No matter what quality you use. Probably better to save an original in another format (tiff, psd, etc.) make changes in that format, then save a copy as a jpeg to reduce the file size.
