29.08.06 Hello all from a new member. I have recently purchased a new Intel Mac Mini with OS X 10.4.5. I installed Adobe Photoshop CS (1) on it and, while the software works as it should, the colour is causing a big problem. Even though the RGB and CMYK values read zero in the colour picker, the White is not White, but instead everything looks like a 20% Magenta - this includes the toolbox and the colour palette as well as any new file opened! And just to further confuse matters, whenever I print out anything with the 'Magenta', it appears as White! I have re-installed the software, but to no avail, it doesn't make any difference. Is it a calibration problem? Can someone PLEASE HELP. Many thanks in anticipation of your valued assistance. Best wishes, John McEvoy.
