Many thanks for all people's help - I have downloaded the trial version - and love it (the cicular marquee tool, the fonts, the fun "cookie cutter", all the fun standard shapes for proucing mats and funky shaped photos). Something tells me I have found my birthday present (which is quite nice timing as my tiral runs out just after my birthday!).
I have got frustrated at not being able to find things in the same place as in PSE1, but as I have only been playing for a short time, hopefully I will learn all the new shortcuts soon!
