hmmz..I am using Gretagmacbeth with the latest huey firmware also
Initially my screen looks a little bit reddish when i first calibrated it, and there seem to be a very obvious "shadow" formed by the mouse cursor when it is over light-coloured areas...
But I realised i had previously manually adjusted my lcd's brightness, So i reset the lcd to factory default, and recalibrated again, and the colour looks much more natural now. The calibrated colours are a bit warmer than the uncalibrated ones.. which appear too cool and bluish.
