I forgot to mention that. The values had indeed changed! Mine was RGB
21,47,31. His is 0,34,14. Both look almost black to me in Illustrator. I can
see the green in Photoshop with the 21,47,31.

I have a feeling the discrepancy we see is a result of the last 2 comments
you make. He's in AI8. He said he selected them all and converted them to
RGB before he sent them to me. When I went to open it, I got the alert that
said there were both CMYK and RGB and what did I want to convert to. I
selected RGB. If I go to File-Document Color Mode, RGB is selected. If I
select any image and go to Filter-Colors, convert to CMYK is grayed out and
I can select Convert to RGB. That shouldn't be, should it?

We were both using sRGB in PS.

Oops. Guess I just revealed my stupidity. :-)

Actually, I just spent many months on the goLive beta team, and I can
honestly say that Adobe does fix bugs; I'm very happy with goLive 6. But
they do have priorities and time to market seems to be top of the list, so
some bugs just take longer to get to than others.

thanks for your help.

AI
