I've just downloaded the trial of CS5 having used Illustrator since before the Creative Suite existed. I'm trying to set up some colours but every time I'm making greys, they are coming out with this gnarly green tint that I don't want. The colour I'm mixing is showing up as regular grey in the colour mixer but in the image I'm working on and the swatch it's showing up with the tint.
That's ridiculous, well now I don't even know where to start. Thanks for pointing that out though, I hadn't noticed myself. I just made a new user on the same machine and opened the same file and everything is as it should be. It could be a problem with the user prefs for Illustrator with that user or perhaps something to do with the display calibration for this user in OS X. I have no idea and at 10pm after a long week I give up : )
