Newbie Illustrator 10 Scripting Issue using Prefab UI

I have used (for the first time) Prefab UI Browser to get this far and now I’m stuck. The script below opens the Color Settings window but I can’t make the buttons work.

When I use the “Perform” function of Prefab, I can see the buttons “change color” but the actual action, Save, Load, Cancel… doesn’t work.

tell application “Adobe Illustrator 10”
activate
end tell
tell application “System Events”
tell process “Adobe Illustrator 10”
tell menu bar 1
tell menu bar item “Edit”
tell menu “Edit”
pick menu item “Color Settings…” --Works to here
pick “cancel” --also tried “click”
end tell
end tell
end tell
end tell
end tell

There is also a “Settings” drop down that selects the actual color profile to use. This is what I am trying to change, but if I can’t even get the individual simle buttons to respond, I know that is going to be extremely difficult.

All Help Appreciated.
