I have no real suggestions I'm afraid Fiona. However, I use CS2 also and I make the basic tweaks in the Raw converter then click 'open' and it automatically opens as Tif in Photoshop.I work on one file at a time, ie I do the basics on one file in Raw then open it in Photoshop to complete any further work and 'save as' [whatever].I have a 6 year old computer and while slow I dont have any probs [touch wood].I'm sure someone on here will have the solution so don't get too down
