I'm helping someone use Photoshop 7 on a new macbook. He's been using Photoshop 7 for about a month now on the new mac and went to make some alterations to 'color settings' and found photoshop seemed to crash. Edit/Color Settings then greyed out - and had to use 'force quit'. Anyone know why this might have happened? What we can try? He has opened color settings successfully before this happened.
