Many thanks guys.
The sites made me wary. I will try the second user route. I prefer old s/w because I want to use it on my laptop. It is only dual core but has a Solid Drive and e-sata so should be doable at CS3/4 level.
FWIW the videos I have made with old versions of Premiere can be seen on YouTube at /cresbydotcom – they are short documentaries but I like to add some textual &/or visual humour. Er make that puns, er would you accept whimseys?
