Nope. PhotoDeluxe HE 3.0, MS Picture It! Express 2.0, MS Photo Editor,
Kodak Imaging, Epson PageManager. THe gamma tool was from Epson (came with
scanner).

Most of my work will be for screen (webpage use). Maybe an occasional
casual snapshot to be printed on the HP 895Cxi DeskJet.

The current color profile is Trinitron 9300K G2.2, with no way of changing
color temp or G.

Problem--I don't thing there are any "quality" monitors I can access.
Perhaps the one I'm using at work right now (Hitachi SuperScan Elite 802,
21") is halfway decent. In fact, is what I have at home (17" Triniton,
.25mm AGP) considered decent?

During scanner installation, that gamma calibrat tool came up, and had to
be done to proceed.
