Thanks to all :) I have saved the link to look at further LP :) Can I be an awful pain and ask what 'colour management' means ? Before I bought PSP I asked around and people couldn't tell me why PS was any different which is why I bought the cheaper alternative. PSP more than equals my skills, but it would be nice to know about PS too :)

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
