Hi Mel,

After setting the components to new RGBs like:

myRGB.red% = aNewRedVal%
myRGB.green% = aNewGreenVal%
myRGB.blue% = aNewBlueVal%

did you then:


This has worked for me. I don't usually use a percented change to set the
NewColorVals; I give them absolute vaules such as 65535 or 40000 or 0, but I
should imagine that any integer values should work.

Good Luck,
Joe Wilkins
