If the proper LUT gets loaded when you launch Optical than some other LUT
loader is doing something for you. Check the ATI control panel for any LUT
or curve corrections options. But I'll bet if you use the Optical start-up
app will solve the problem for you. The start-up LUT loader isn't that bad
but a Band-Aid fix for sure.
